Write a Python script to convert an svSolver .sjb XML file into an svFSIplus solver input XML file

[ktbolt]

Use Case

There are several hundred svSolver jobs in the Vascular Model Repository. It would be useful to have a Python script that could convert an svSolver .sjb XML file into an svFSIplus solver input XML file.

The svSolver .sjb XML file is created by the SimVascular Simulation Tool.

I've written the Python script convert-sjb-to-xml.py that converts an svSolver sjb file into an svFSIplus.xml file

convert-sjb-to-xml.py --sjb-file=../demojob.sjb --mesh-directory=mesh-complete --flow-file=lumen_inlet.flow

tested on the Demo and Cylinder simulations.

The --mesh-directory parameter is needed to determine the wall files which are not given in the sjb file.

The --flow-file parameter is needed because the svSolver has an input flow file that is different format than the one used by svFSIplus.

There are lots of hard-coded parameter values in the <LS type="NS"> section that will probably need to be modified for a specific type of simulation.

This is very helpful! Right now the test case is small-scaled computation especially using PETSc library. The GPU acceleration library AmgX could also be integrated basing on PETSc. For example, AmgX wrapper tool.
