A Method to Determine Element Size Based on Optimal design

The element size affects greatly the simulation result during finite element analysis of structure, in ANSYS. A cantilever beam is simulated respectively with the element size of 0.008m and 0.002m. The result illustrates that improper element size will lead to irresponsible simulation result. The optimal design of ANSYS is introduced and a new method is put forward to determine the element size by using optimal design. The question of determining element size is solved.
