I am comparing theoretical with results from a simulation and I am having problems determining where I have gone wrong. Attached is file containing the Excel file with my theoretical calculations and the Solidworks file. The shaft is fixed at both ends and has a stainless steel material. Theoretical results say that the deflection at the center is 0.0255 m while in Solidworks it says 0.00529 m. I have gravitational loading enabled and I am using the same values for Young's modulus and density. Any help will be greatly appreciated.
