negative cell volume detected while running ANSYS Fluent UDF
 
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
