Dear Foamers,
I try to use interFoam to simulate vortex-induced vibration of a circular cylinder with/without free surface. The result for VIV without free surface and for flow arround the stationary cylinder with free surface looked good. But the result for VIV with free surface was quite weird. The cylinder did a periodic oscillation and the drag coefficient looked ok while the lift coefficient went with weird fluctuations. I attached the body motion and force coefficient. Could somebody help? What could be the problem? Best regards, Z.F. |
