The sources of errors in first-order FEM for electrostatic lenses
Creators
Description
Discretization errors in the first-order FEM for rotationally symmetric scalar potential in electrostatic lenses are studied for the case of irregular meshes and in the vicinity of electrodes. The expression of these errors has been obtained with the help of MAPLE. It helps us to understand the error estimates of the potential and gives us guidelines for proper mesh generation
