the only xml. data that i have for the project is for adding the material. Could it be a problem from using the shared topology, i formed 2 solid bodies into one part and i use shared topology for combining it. I dont think i need to give another "contact" between the two bodies. For the imported  force load, i exported the nodes number and location from the face to .xls file. Firstly i select the face as named selection and then i used this function "Create  Nodal Selection" from the named selection. I added two force in X and Y for each nodes and then import it again to Ansys using the External data in .csv file.

Do you have any tips what can i try  at this point? I need to calculate vector principal stress from the whole workpiece.
