svFSIplus (C++ solver) produces different stress result from svFSI (Fortran solver)

Hi SV developers,
Greetings! We have been trying to run the FSI simulation using svFSIplus and svFSI. In our simulation files, we found that while both solvers are able to give us stabilized results, the Von Mises stress and the Cauchy stress are 10 times lower for the results returned by svFSIplus. The difference in resultant stresses persists if we change the constitutive model from HGO to NHK. When you have time, could you look into this issue? I really appreciate your time and effort.
