I am doing 2D orthogonal cutting simulation in ABAQUS for aluminum. Reducing mesh size up to 0.08 mm reduces the error to 3% but further reduction leads to increase in error from 3 to 39%.
Why I am having this trend? How to solve this?
Why direct inversion of mutivariate regression equation is not preferred and instead optimization techniques are used?
