segfault when adding traction using svFSIplus

Hi SV developers, I'm trying to solve a prestress problem using svFSIplus, and I encountered "segfault" if I apply traction on one of the surfaces. The file for traction seems to be fine. If I remove the code for adding traction, the simulation runs fine, so I assume it's a syntax error. Could you g...

Documnation about meshmixer and simvascular meshing for svFSI

Hi I have facing issue in meshing of lumen wall from inner wall of aorta. Initially I was following the steps as discussed in Simvascular documents where the meshing procedure of wall and lumen is given using meshmixer and simvascular. I missed this documents link, can any one please share this link...

ROM 0D solver error message

Hello!

I tried to run a 0 order ROM simulation, but I got an error message like this (attached as screenshot). I remembered to download the python file from github and put it in SimVascular's program folder, but still it does not run the simulation. Any suggestion would be appreciated!

Thanks
