khushbu.bhavsar92 New Member Join Date: Mar 2016 Posts: 8 Rep Power: 10	Hi, I am trying to simulate vortex induced vibrations past a 2D cylinder using ANSYS Fluent. I am new to dynamic meshing, I activated the 6 degrees of freedom solver along with smoothing and re-meshing. I keep getting the error saying negative cell volume detected. I tried reducing the time step and increasing the stiffness, it still shows the same error. Could someone please help me with this problem. I appreciate your time. Thank you
