I am trying to apply the dynamic mesh to simulate the translational movement of the tool in friction stir welding as it is represented in a conical wall. On the other hand the deforming zone represents only the strip in the middle of plate and the motion was specified by a UDF. Although, I used different approaches (diffusion, spring) and played with the parameters and the time step, I am still receiving the error of (negative volume cell zone) after number of time steps. any recommendations?
thanks in advance

Hi
The best thing to start with is working on enhancing the mesh quality and then defining a n appropriate time step size. I would also recommend using both smoothing and remeshing.
