Default six dof help urgently required
Posts: n/a
hi guys,

i am trying to simulate the underwater store seperation problem using moving defroming mesh. when i preview the mesh using six dof solver coupled via udf the mesh motion is fine and remeshing and smoothing is ocuuring at every timestep. But when i iterate the solution and compute the forces on the store, fluent gives negative volume error after three or four time steps and countinuity diverges. After the error if you display the grid the body pulls the grid and its motion is unacceptable.

please help. with best regards, sam

I think there is a problem of compilation with the UDF.
