fedoo.constraint.SurfaceForce.get_node_results

SurfaceForce.get_node_results(operator, U)

Return some node results based on the finite element discretization of a differential operator on a mesh being given the dof results and the type of elements.

Parameters:

• operator (DiffOp) – Differential operator defining the required results

• U (numpy.ndarray) – Vector containing all the DoF solution

• Return (numpy.ndarray) – A Vector containing the values on each node. An interpolation is used to get the node values from the gauss point values on each element. After that, an arithmetic mean is used to compute a single node value from all adjacent elements. The vector lenght is the number of nodes in the mesh
