Abstract
We perform numerical experiments to assess the performance of generalized elements that partially have a physical domain in the context of the finite cover method (FCM). The partial physical domain of interest is in a rectangular or an arbitrary shape and the comparison is made with the standard finite element model (FEM). We also report the appearance of cancellation errors in assembling elemental matrices and vectors and in treating essential boundary conditions. After making a simple convergence study, we conclude that the performance of generalized elements in the FCM are equivalent to or slightly superior to that of the FEM.
