how can I find the mid-nodes
Posted Oct 5, 2009, 6:30 PM EDT Mesh Version 4.2 1 Reply
I am using Taylor-hood ( second-order Lagrange) FEM to solve some PDEs, thus I need to number the nodes including the mid-point at each edge of the triangular element. The fem.mesh.t and fem.mesh.p only offer the positions and informations of the vertices, not including the mid-nodes.
How can I determine the positions of the mid-nodes and give them an order, like fem.mesh.t and fem.mesh.p.
Any help would be appreciated.
