simmetrixModel2Parasolid

simmetrixModel2Parasolid is tool to convert native Simmetrix models (.smd files) to Parasolid (.x_t files). It uses the Simmetrix Parasolid interface. To use on SCOREC rhel9 machines, load the modules:

module use /opt/scorec/spack/rhel9/v0201_4/lmod/linux-rhel9-x86_64/Core/
module load gcc/12.3.0-iil3lno mpich/4.1.1-xpoyz4t cuda/12.1.1-zxa4msk
module load module load simmetrix-simmodsuite/2025.0-241016dev-vafjs2q

and then run the tool:

 /lore/hasanm4/wsources/simModel2parasolid/build/simModel2parasolid simModelName.smd parasolidName.x_t

Convert Parasolid to Simmetrix

To convert Parasolid files (.x_t, which can be also exported from NX parts) to Simmetrix models (.smd):

1. Load the required modules:

module use /opt/scorec/spack/rhel9/v0201_4/lmod/linux-rhel9-x86_64/Core/
module load module load simmetrix-simmodsuite/2025.0-241016dev-vafjs2q
module load pumi/develop-simmodsuite-2025.1-250507dev-int32-shared-g2attww
module load simmetrix/simModeler

2. Open simmodeler GUI and import the Parasolid file. Go to Prepare tab and select Create Model or Make Model or Create Nonmanifold Model depending on the version. Make sure to select Nonmanifold. Now, save the model as .smd file. This will create a new Parasolid file model-nat.x_t in the same directory.
3. To use this model in simmetrix tools, it needs to be translated to a Simmetrix native model. For that, run the following command:

simTranslate model-nat.x_t model.smd model-translated.smd

and use the model-translated.smd file in the simmetrix tools.
