Solid viscosity bug #95

Closed aabrown100-git closed 1 year ago

aabrown100-git commented 1 year ago

There appears to be a bug in the implementation of solid viscosity in both STRUCT and USTRUCT. As the value of viscosity increases, the convergence of the Newton iteration deteriorates or fails altogether. @vvedula22 @LeiShi3374 and I have been working on fixing this issue. The latest implementation can be found at this commit on Vijay's fork: https://github.com/vvedula22/svFSI/commit/a902e8f7611c82dc17a674c91e35a55ea0d751b3.
