Load sample_mesh works properly with the same build.
In #33, StaticMeshBase::calc_max_nface() is implemented using switch case:
// FIXME: This switch is sub-optimal.
switch (cltpn(it))
{
case 1:
max_nfc += PointCellType().nface();
break;
case 2:
max_nfc += LineCellType().nface();
break;
case 3:
max_nfc += QuadrilateralCellType().nface();
break;

max_nfc += TriangleCellType().nface();
break;

break;
case 7:
max_nfc += PrismCellType().nface();

case 8:
max_nfc += PyramidCellType().nface();

}There should be a better way to do it and changing the CellType classes is allowed.
The viewer does not yet have window title and icon.
The viewer binary invokes pybind11::scoped_interpreter() in the beginning of the process. From
modmesh/cpp/binary/viewer/viewer.cpp
Line 52 in e2de7ce
modmesh/cpp/modmesh/python/common.cpp
Line 65 in e2de7ce
It might not be too far away for us to make the viewer binary work like a Python interpreter, i.e., equip with interactive REPL in text console. Then the binary can work as both an entry point of the GUI and the interpreter.
On a Mac of an older version, supposedly below 12, the viewer app is likely to crash with the RHI rendering backend.
In my case, the following error messages first appeared while running sample_mesh and the viewer app failed to render the edges and axes as expected.

Even, a while after the running, the viewer app straight crashed with a segmentation fault.
As specified in the document (https://doc.qt.io/qtforpython/overviews/qt3drender-porting-to-rhi.html), the workaround is to switch the Qt6 rendering backend from RHI to OpenGL by setting the environment variable QT3D_RENDERER=opengl before running the viewer app.
Moreover, the doc also lists several limitations of RHI rendering backend which may be the culprit of the crash.
Sidenote: The issue originated with a macOS of version 11.6.8 and Qt of version 6.3.1.
Port build_ghost() from SOLVCON: https://github.com/solvcon/solvcon/blob/8dd74fa848b8d14d7796138ce199d0ae2e70235f/libmarch/include/march/mesh/UnstructuredBlock/class.hpp#L312
This is part of #33.
When the mesh is shown in the viewer in the first time, everything looks OK:
But showing a (slightly) different mesh using modmesh.view.show() does not remove the first mesh and have the first and second overlaid in the widget:
There should be a way to avoid the unwanted overlay.
Currently the viewer is using a primitive widget to take Python code to run and it is not easy to use:
There should be a REPL widget working like the Python REPL or iPython.
run button for the command line, it will be more straightforward.master after #174 is merged-DMODMESH_USE_PYSIDE=ON./build/clion/debugtidy/cpp/binary/viewer/viewer.app/Contents/MacOS/viewerApp of the viewer and load euler1dThe app is loaded without Python exception
The app is loaded and can be executed without problem, but terminal prints Python exception thrown from matplotlib:
Traceback (most recent call last):

The class StaticMeshBC (boundary-condition treatment) is only available in C++. We should make a way to populate the BC objects in StaticMesh from Python.
We may also consider to use polymorphism on the BC classes.
SimpleArray currently supports only fundamental types. Before supporting struct arrays, I would like to explore how it can support columnar groups of arrays.
The columnar groups organize arrays in the following way:
struct StructOfArray
{
SimpleArray<int32_t> m_field1;
SimpleArray<double> m_field2;
};This is also the so-called structure of arrays. If we treat the fields as the "rows" in a 2D array, the data in the group are organized like the "column-major" format of 2D arrays. This is why we use "columnar" to describe this kinds of data structure.
We hope modmesh provides a nice way to support the columnar data structure in C++ and allow easy access in Python, while it is possible to manually write code to construct the above StructOfArray, but the code is ad hoc and convoluted.
3D elements include tetrahedron, hexahedron, prism, and pyramid.
for Linux, I always need to add the line manually to make QT work. Maybe have a variable to specify the QT path and also try to guess where is QT?
set(CMAKE_PREFIX_PATH "/home/user/Qt/6.3.2/gcc_64/lib/cmake")
The shock tube problem (modmesh.onedim.euler1d.ShockTube) is a classical compressible flow problem. It uses a numerical solver along with an analytical solution.
The numerical solver is supposed to be high-performance but it is not yet optimized. Before optimization, profiling should be done. We do not yet have a useable profiling system in modmesh, but there is a prototype: https://github.com/solvcon/modmesh/blob/master/cpp/modmesh/profile.hpp .
This issue is to track the augmentation of the prototype to a useable profiling system. It does not need to be comprehensive, but should help understand the performance of the shock tube problem.
At the time being the only way to render 3D objects is to use Qt3D API. This ticket is opened to prototype using OpenGL directly in Qt. The first step is to create a Qt widget allowing that.

I'd like to start from "building modmesh on Ubuntu with devenv".
I built the viewer with the latest code (commit 2774f90) and get segmentation fault by running the viewer.
Build and execution environment:
Build step:
export pybind11_DIR=${HOME}/work-my-projects/solvcon/modmesh-installation
export CMAKE_PREFIX_PATH=${HOME}/Qt/6.2.4/gcc_64

make viewer VERBOSE=1 BUILD_QT=ON CMAKE_BUILD_TYPE=Debug CMAKE_ARGS="-DPYTHON_EXECUTABLE=$(which python3)"
Execution result:

I guess it's not the only place to have the issue.
Add the prototype projection method code to the branch projection.
The projection code may use constant-space two-dimensional Cartesian grid. It should use SimpleArray. A unit test should be available for it.
OS: Ubuntu 20.04.4 LTS
sample_mesh runs with no crash regardless of how many time it's executed.
sample mesh crashes when its load twice in a row.

The viewer works properly loading linear_wave no matter how time in a row
For indexing elements outside a mesh we need the "ghost" elements. The ghost elements will use negative integer.
Allow SimpleArray to allow negative index in the first index.
Add basic menubar to the viewer.
At the time being, the (C++) SimpleArray class template is wrapped to Python by using distinct wrapper classes (template instantiations) for each of the fundamental value_type of interest:
WrapSimpleArray<bool>::commit(mod, "SimpleArrayBool", "SimpleArrayBool");
WrapSimpleArray<int8_t>::commit(mod, "SimpleArrayInt8", "SimpleArrayInt8");
WrapSimpleArray<int16_t>::commit(mod, "SimpleArrayInt16", "SimpleArrayInt16");
WrapSimpleArray<int32_t>::commit(mod, "SimpleArrayInt32", "SimpleArrayInt32");
WrapSimpleArray<int64_t>::commit(mod, "SimpleArrayInt64", "SimpleArrayInt64");
WrapSimpleArray<uint8_t>::commit(mod, "SimpleArrayUint8", "SimpleArrayUint8");
WrapSimpleArray<uint16_t>::commit(mod, "SimpleArrayUint16", "SimpleArrayUint16");
WrapSimpleArray<uint32_t>::commit(mod, "SimpleArrayUint32", "SimpleArrayUint32");
WrapSimpleArray<uint64_t>::commit(mod, "SimpleArrayUint64", "SimpleArrayUint64");
WrapSimpleArray<float>::commit(mod, "SimpleArrayFloat32", "SimpleArrayFloat32");
WrapSimpleArray<double>::commit(mod, "SimpleArrayFloat64", "SimpleArrayFloat64");And in Python, the construction of SimpleArray needs to use the specific type names:
sarr = modmesh.SimpleArrayFloat64((2, 3, 4))
self.assertEqual(2*3*4*8, sarr.nbytes)
self.assertEqual((2, 3, 4), sarr.shape)
self.assertEqual((12, 4, 1), sarr.stride)It will be desirable to avoid the fundamental type name (Float64) in the array type name, so that the Python code can be written as:
sarr = modmesh.SimpleArray((2, 3, 4), type='float64') # or dtype='float64'
self.assertEqual(sarr.ndarray.dtype, np.float64)We may choose to mimic the numpy API by using dtype or invent our own way.
Struct arrays are a different topic. This issue focuses on the arrays of the fundamental types.
We want a simple way to visualize the unstructured mesh and the elements. It may be fun to create a GUI for it.
See https://doc.qt.io/qt-6/qt3dcore-qattribute.html#vertexSize-prop and #167, #170. We should understand what does setVertexSize() do and use it in a right way.
This proposal suggests having a configuration file for turning on/off features in Modmesh.
Currently, we may use Python script to set up some configs during runtime, such as setting modmesh.view.app.pycon.python_redirect = False, but it's inconvenient to do it again and again when we are doing some testing.
The steps should be:
config.{format} in json or ymal format.class ConfigConfig and Modmesh initializes everything according to ConfigConfigThere should be no overhead for Modmesh with this proposed change. This change may also benefit the later web server feature since we can expect some configurations may be required.

The project has C++ and Python parts. The C++ part plays the role of the computing engine, while the Python provides an easy-to-use platform for application.
A reasonably organized system has been developed in C++, but there is not a place to house Python code for application. A sub-package (under modmesh) should be created to house the application code.
I didn't include the Q_OBJECT macro in QObject sub-classes (the R-named classes). It is simply an overlook.
Before the macro is added to the QObject sub-classes, we should make sure we know how to correctly add it. This issue is filed to keep track of the fix.
This is a continuation of #104 . The control of RPythonCommandTextEdit in RPythonConsoleDockWidget currently only allows single-line editing although the underneath qt widget is capable of multi-line control.
The unit test has a 2D example mesh:
Line 82 in dc0a9f6
The new prototype viewer should help creating and inspecting the mesh.
This issue is opened to track the ongoing work of porting to windows.
The view widget should use an axis marker.
Provide better support for the Python wrapper of the class template SimpleArray to get the data ndarray through the memory buffer.
>>> import modmesh as mm
>>> import numpy as np
>>> sarr = mm.SimpleArrayFloat64((2, 3, 4))
>>> ndarr = np.arange(2*3*4, dtype='float64').reshape((2, 3, 4))Using Python ellipsis should copy the data in the memory buffer from ndarr to sarr, but it does not work yet:
>>> sarr[...] = ndarr[...]

Currently the modmesh-viewer has only Ubuntu build test. It will be convenient to have macOS (12) viewer build as well.
The current camera control uses vanilla Qt3DExtras::QOrbitCameraController and should be improved. The camera control is a critical component in the viewer. It at least needs the following functions and more:
Per discussion on 220517 we all agree to do this. See https://hackmd.io/ZEN4vslFSs-40rGKaIgA2g?view
I have no luck when building the latest codebase (commit 0a1f538 ) with my branch ( see PR #177 ) . I guess it may be my configuration since the CI of Ubuntu passed. I will check in more details later to see what's going on.

We are adding more and more features to the project and there is not yet a system to manage the settings of the features. A feature-toggling system should be implemented to house and control the features that were and will be added. Related discussions are in #165 .
The feature toggles should support two types of parameters:
Tasks:
FixedToggle to house compile-time-named, runtime-initialized values. Addresses of the values are determined by the compiler/linker and it does not take table lookup. It does not use hierarchy.DynamicToggleTable to house the key-value pairs determined only during runtime. Access requires table lookup. The keys are dynamic strings. It support hierarchical access.After this issue is done, update modmesh engine and apps to use the toggles (create new issues to track the follow-up work).
The screenshot feature should allow:
In https://github.com/solvcon/modmesh/pull/65/files#diff-7c21257cbc1fa4b8ffea665a0917abdd7861abf2562486ca4b2d6d3f26122e84R121, to show the wireframe of the tetrahedron, a lot of duplicated edges are used. For data integrity and reduction of memory and runtime, the duplicated edges should be removed.
I think it's a good idea to add code in StaticMesh object to produce the sequence of edges.

Port the function calc_metric() from SOLVCON: https://github.com/solvcon/solvcon/blob/master/libmarch/include/march/mesh/UnstructuredBlock/calc_metric.hpp to complete build_interior().
This is part of #33.
