Trying to get the first OpenRadioss starter script worked about openradioss

[MarianBulla]

Hello,
thank you very much for trying to build a OpenRadioss model.
In your model, there are some syntax errors:

• Floating point numbers have 20 digits space: Review the nodal coordinates.
• Tetra elements are using the keyword /TET4/ (instead of /BRICK/)
• 3-node-shells are defined by the keyword /SH3N/
• 2nd line in the property definition is used for the name of that properts (= string)
  One suggestion is to use existing example models for testing you script.
  Anyway, find attached your corrected model, below.
  Hope I could help you ?
  Thanks and best regards,
  Marian

Hello, Could you guide me on how to resolve the warning below? The engine input file radioss_welsim_0001.rad does exist in the same folder as the radioss_welsim_0000.rad file, the starter executable warns the file for not existing. Thanks.

WARNING ID :   1589
** WARNING 4-NODE TIME STEP
DESCRIPTION :  
   SOLVER INPUT FILE radioss_welsim_0001.rad or radioss_welsimD01 NOT FOUND -> CAN NOT CHECK FOR /DT1/BRICK
   Time step initially output in file *_0000.out may be different than the one used during the computation. 

my running script is:

set OPENRADIOSS_PATH=D:\WelSimLLC\executable25\OpenRadioss
set RAD_CFG_PATH=%OPENRADIOSS_PATH%\hm_cfg_files
set RAD_H3D_PATH=%OPENRADIOSS_PATH%\extlib\h3d\lib\win64
set KMP_STACKSIZE=400m
set PATH=%OPENRADIOSS_PATH%\extlib\hm_reader\win64;%PATH% 
set PATH=%OPENRADIOSS_PATH%\extlib\intelOneAPI_runtime\win64;%PATH%
set OMP_NUM_THREADS=32

set startFile=D:\WelSimLLC\executable25\501_ice_cube_sliding_simple\proj5\radioss_welsim_0000.rad
set engineFile=D:\WelSimLLC\executable25\501_ice_cube_sliding_simple\proj5\radioss_welsim_0001.rad

Hello, this is just a warning, that the STARTER is not able to estimate the timestep (desired by the user). So, the naturall one will be used and can differ from initial estimation.
You can ignore it for the first shot.
Hope it helps you ?
Thanks and best regards,
Marian
