How to calculate Failure Load on ANSYS?

I'm doing my master's project, which aims to treat a fracture of the femur in elderly women. As so, I have a design of a scaffold and I would like to use ANSYS to calculate the failure load, compressive modulus, and stiffness. Can someone please help, as I have no idea how to perform it?

The load on the top surface of the scaffold would be 945.3N. It is necessary to divide this value by the surface?

Thank you so much for any help or tips you can give me!
