Hi,
I have a question about generating meshes for a moving wall flow simulations. According to the documentation at https://simvascular.github.io/documenta ... ardio.html it seems there are 4 steps:
1. Segmentation
2. Surface and Volume Mesh Generation using surface_main.py and volume_mesh_main.py
3. Mesh Registration using elastix_main.py
4. Interpolation and motion calculation using interpolation.py

Does the interpolation.py script generate interpolated volume and surface meshes, or does it only calculate the mesh motion and write it to a file? Also, when running the simulations, should I give svFSI meshes for every time point in the simulation, or just the meshes for the first time point and the motion file?

Hi Moses,

The interpolation.py calculates the mesh motion from the registered surface meshes obtained from elastix_main.py. When running the simulations, you would need to use the mesh at the first time step and use the motion files to prescribe displacements over time. You can find an example case here: https://www.vascularmodel.com/additionaldata.html.
