Hi,

Thank you for information. Unfortunately after changing the settings on the magnitude of the deformation it came with different errors. I have changed the design of the wheel in Spaceclaim ANSYS to merge and create fewer faces, once I added the supports and loads to find the total deformations and stress before starting topology optimization on the model the program came with one error which is shown in the second image for this discussion which says (**Your product licence has numerical problem size limits you have exceeded these problems size limits and the solver cannot proceed ansys**).

At the moment I am using ANSYS Workbench 19.1 on a Dell precision tower 5810 which should not be a problem calculating it, I have section the model in half and tried but unfortunately it did not work. I have read other discussions where Peter and others responded to the same problems, I followed the steps that was in the discussions to resolve the problem, but I am not quite sure where the error is.

Does anyone know how to solve this problem, I look forward for any response.

Thank You.
