Yes, the idea is to calculate first with an 8 nodes mesh and then refine it to see how the results improve. After trying sizing to edges according to course instructions, I couldn't reach the required geometry. I tried making the mesh with face mesh instead, sizing the elements to 1 meter, and I got this geometry with the error message Some local body element sizes are larger than the global maximum size, This can cause bad quality elements. I would like to know how to solve this error in ANSYS 2020R2. You can see this in the following screenshots:nn
