  Hi all. I use a dynamic mesh (remeshing+smoothing) using a 6dof model, the sover density-based. Mach number is 1.2
  Upon starting the simulation I get an error which prompt fluent crash
  
  Updating mesh at time level N...

  Any suggestion? For some strange reasons the same case with the same udf it works with the pressure based solver in transonic

  Hello,
  have you tested your case with density-based solver but without Dynamic Mesh?
  We should determine if DM is the issue or something else in the case.
