Farqy New Member Join Date: Apr 2023 Posts: 2 Rep Power: 0	Hi All, I've trying to vary the volume of cylindrical mesh. Four patches are used for the circumference and one each for the back and front (effectively the cavity case mesh but round). I'm using moveDynamicMesh with oscillatingDisplacement patch type for each of the circumferential patches. Depending on the oscillation amplitude and which patches move, the simulation `falls-over' whilst running, returning the error: Floating point exception (core dumped) Any help would be greatly appreciated, thanks. Regards
