pimplefoam crashing while validating FSI2 of Turek-Hron FSI benchmark
 
Hello foamers,
I am trying to validate TurekHron FSI benchmark with my FSI model.
I have used Openfoam v7 to solve the Fluid part and CalculiX to solve the solid part and coupled them both with precice.
FSI1 in which Reynold's number is 20 runs perfectly and gives accurate results.
While FSI2 in which Reynold's number is 100 sets up perfectly but crashes after a while. I am sure CalculiX or precice isn't the issue.

I cannot figure out what the problem is.
I am attaching the successfully ran steady case here and partially ran Unsteady case here

The log files for the fluid are in the directory itself.
I have attached an instructions text in case anyone is not informed enough to use precice environment.

Any help will be very much appreciated.

Thanking you in advance,
Nithin
