Hello Foamers,
I'm trying to symulate a vertical beam a cross flow, where the flow is driven by a volume force and the boundary condition in the fluid domain are cyclic. I've started from the beamInCrossFlow tutorials in the FSI package fro the foamextended 4 and I succesfully added the source term for the fluid equtions, but I have problems whith the cyclic conditions. After setting the inlet-outlet cycling bc, when I lunch the fsiFoam solver I get this error: """ Code:
Create time Create dynamic mesh for time = 0 Selecting dynamicFvMesh dynamicMotionSolverFvMesh Selecting motion solver: displacementLaplacian --> FOAM FATAL IO ERROR: keyword global is undefined in dictionary "/beam2/fluid/0/pointDisplacement::boundaryField" I think that the problem is somehow in the cyclic condition in the fail pointMotionU. Someone of you has some experience about this kind of problems ? Thank you in advance |

Actually I have managed to correct the error about the global patch (it was a different way to define cyclic patch in foamextended that of).
But after the first iteration the solver blow-up because the patch in the direction of fluid are not constrained (i guees) because in the pointMotionU I have to set the bc as cyclic. So anyone have a motion solver that will do the job ? |
