When i define a boundary condition or a point mass in my models, i enter the related values e.g. 0.324 mm or 4,206 kg. Ansys mechanical accepts these values. But when i close my model and reopen it, Ansys shows the above values as 3241 mm or 42060 kg.

Does anyone know why this occur?

Thanks in advance.

Just to be sure, could you run the simulation once (with the correct values) , save it, close it. Then reopen the model, clear generated data and evaluate results again. Now do you see a difference between results of the first and second run?

If you mean clearing post-processing results and re-evaluating, there is no problem in that. But when i close a converged model and reopen it the displacement boundary conditions change as i stated before. If i clear the result and run the analysis again,(with 3241 mm displacement bc) then the analysis diverges in the first substep.(3241 mm being an absurd value i believe).
I may have solved the issue though. This may be due to my windows settings. I was using comma as decimal seperator. When i have changed it to dot, the problem was solved.
Thanks for your concern.
