Posts: n/a
Dear friends: I have some confustion about the boundary in fem method. for example, i want to solve a simple heat conduction problem in a rectangular region. the left and right wall take a constant temperature bc, and the up and bottom wall take a insulation bc. so what about the node at the corner. regards

The matrix will be smaller and likely better conditioned if you use a Dirichlet condition at transition nodes.
