hi
i model a shell in fortran code,and i calculate normal vector and deformation gradiant for it,but somewhere in the solution the z-direction of normal vector become so small and it cuase the determinant of defo-gradiant become so small and near zero and for inverse of it the element become so big and cause a problem,i want a way to avoid this,what should i do?
