Modelica Standard Library

Free library from the Modelica Association to model mechanical (1D/3D), electrical (analog, digital, machines), magnetic, thermal, fluid, control systems and hierarchical state machines. Also numerical functions and functions for strings, files and streams are included.

Library description

Package Modelica is a free library that is developed together with the Modelica language from the Modelica Association. It is also called Modelica Standard Library. It provides model components and standard component interfaces from many engineering domains. Each model comes with documentation included. The generous license conditions allow usage in commercial products.

Note, the usage of a Modelica library requires a Modelica simulation environment, see the tools page, and that such an environment usually already includes the Modelica standard library. It is possible that the demo version of the commercial tools will not allow to simulate non-trivial examples from the library.

Current release

Modelica Standard Library v4.0.0 (2020-06-04)

dcptestgenerator's Issues

Build issues

In order to build this tool (in it's master branch version) you have to make some adjustments

• Modify pom.xml adding the next block in the dependencies section

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
    <version>2.3.0</version>
</dependency>

• Build the software using mvn package. If you are running in a 64 bit machine, the launch4j phase will probably fail. To solve this:

sudo apt-get install binutils-mingw-w64-x86-64
ln -sf /usr/bin/x86_64-w64-mingw32-ld ~/.m2/repository/com/akathist/maven/plugins/launch4j/launch4j-maven-plugin/1.5.1/launch4j-maven-plugin-1.5.1-workdir-linux/bin/ld
ln -sf /usr/bin/x86_64-w64-mingw32-windres ~/.m2/repository/com/akathist/maven/plugins/launch4j/launch4j-maven-plugin/1.5.1/launch4j-maven-plugin-1.5.1-workdir-linux/bin/windres 

The system I'm running on is

Wrong sequence id after starting the simulation

pdu_seq_id is reseted after sending a STC_run. This causes an error in the DCP-Slave implementation. The pdu_seq_id of DAT_input_output should be 326.

xsd loading problems

After successfully building the tool you end up having the following issue

bgarciagonzalez@28APO3997:~/DCPTestGenerator/target$ ./XmlTemplateParser.exe 
run-detectors: unable to find an interpreter for ./XmlTemplateParser.exe

If you try the shaded jar the getClassLoader is not able to access its own resources

bgarciagonzalez@28APO3997:~/DCPTestGenerator$ java -jar target/PathExpander-0.0.1-SNAPSHOT-shaded.jar -dcpx pid.dcpx -UDP

you can tweak that paths to point outside the jar but you wont get far

error while parsing dcpx with binary data type

Seems like the tester can not handle dcpx files with binary data types.
The error message disappears if the data type is changed to string.

Wrong Test Procedure if dcpx contains string data types

Generated a test procedure with a dcpx Slave Description that contains a string input variable.
The TestGenerator sends the wrong source data type.
source_data_type should be string.

Testfile generation error if parameter is tunable

Test-File is not generated if a parameter is tunable.
Generation works if the variability is set to fixed

<Variable name="speed" valueReference="1" description="speed" variability="tunable" >

		<Float64 start="0 " />
