How do you refine body fitted Cartesian Mesh ?

  I am doing an AM simulation on workbench which only works with body fitted Cartesian mesh for some reason.nAnyway I have tried numerous methods and times to refine the mesh using sizing etc and they do nothing. Comes up with tick but mesh is unchanged. Only thing that works is reducing element size for whole model but this make CPU time far too highnI just want to refine high stress/strain concentration areas not the whole part. Does anyone know how to do this? (with body fitted Cartesian)n

  Screenshots won't show anything but I will try to explain better:n1) The only method of meshing that allows an AM simulation to solve in workbench is a body fitted Cartesian mesh (all others such as body sizing etc results in errors)n2) I am wanting to refine this mesh as my simulation is not converging and solve time is already 12hrs +n3) I am only wanting to refine in the corners where high stress/strain regions are present n4) I have tried a number of the mesh tools such as edge sizing to refine my mesh however these do not have any affect unless I suppress the body fitted Cartesian. It is like the body fitted Cartesian overwrites any other mesh sizings/parametersn5) This leaves me with only being able to change the element size for the whole specimen which I do not want to do because of the large solve times involved with much greater number of elementsnDoes anyone know how to stop body fitted Cartesian overwriting all other mesh types? Or how to refine a body fitted Cartesian mesh (other than just reducing element size for full part)?n

  I am facing the same problem, did you found any solution for this problem?
