I am new in multi-grid method. However, all tutorials I read are 2D Poisson equation on uniform mesh. In practices, the mesh is often stretched, but have no idea how to implement multi-grid method on a non-uniform mesh. Could you please give me some hints or recommend some relevant books or tutorials for this? Many thanks.
