Pressure jump and vanishing solver
Dear all,
we are simulating fluid-structure interaction (FSI) using OpenFOAM (a modified interDyMFoam solver) and an external structural solver, coupling them via MPI. After a certain simulation time one of the OF solvers (either for cellDisplacement or U) "looses" one component. Usually (in quasi 2D) we get something like Code:
DICPCG: Solving for cellDisplacementy, Initial residual = 5.561218854736067e-07, Final residual = 5.561218854736067e-07, No Iterations 0 Code:
DILUPBiCG: Solving for Uy, Initial residual = 0.006568920370747625, Final residual = 2.648992650684406e-10, No Iterations 2 Has anybody ever experienced something like this? Any hint or rough guess? Best regards Silvan |
