Description

I am running the same structural test cases (LV passive filling) using svFSI and svFSIplus, but the results (e.g., pressure on the surface) are noticeably different. We tested several potential simulation parameters, and viscosity, the Holzapfel material model, and fiber direction seem to be leading to these differences.

Reproduction

Running the three test cases above using svFSI and svFSIplus respectively.

Expected behavior

The two solvers give the same results.
