If you just would like to extract Faces from 3D elements, you can work with Validade > Faces (https://2024.help.altair.com/2024/hwdesktop/hwx/topics/pre_processing/model_setup/free_faces_find_t.htm).
But if you would like to extract the surface stress from solid elements, and if you are working with OptiStruct, you can check the INT0 option from PSOLID card (INT0)
Integration points are located on the surface of both first and second order solid elements for better evaluation of results
Linear and Nonlinear (Small and Large Displacement) analysis are supported. Additionally, the STRESS(GAUSS)=YES entry should be specified in the model for this option.
