Movingwallvelocity
Nettet19. jul. 2016 · The cylinder is moving! Luckily there is a handy boundary condition for this in the U file: cylinder { type movingWallVelocity; value uniform (0 0 0); } For a typical simulation using pimpleFoam a p and U file would be all that are required. However, since we are doing a moving mesh simulation there is another parameter that must be solved … NettetBC’s - slip and reflecting walls, movingWallVelocity for the cube Initial values Erik Ekedahl OpenFOAM 13/18.
