We also show that variationally imposing the Dirichletīoundary conditions via Nitsche's method leads to suboptimal solvers. The best results are achieved byĮxactly enforcing the Dirichlet boundary conditions by means of an approximateĭistance function. The output of the neural network to exactly match the prescribed values leads We show through several numerical tests that modifying Such conditions are usually imposedīy adding penalization terms in the loss function and properly choosing theĬorresponding scaling coefficients however, in practice, this requires anĮxpensive tuning phase.
