I would like to ask if it is possible to display scalar, vector or tensor values at distinct nodes in a finite element mesh.
To make things clearer, there exist finite element formulations where not all nodes have the same number of degrees of freedom. Consider the case of a 20 node hexahedral element. In a so called u-p formulation all 20 nodes have 3 displacement degrees of freedom (one for each x, y, z axis) but only the 8 corner nodes have pressure degrees of freedom. For this particular case, i know how to display the vector of displacements for all the nodes. But since only the corner nodes of each hexahedron have pressure degrees of freedom how can I instruct paraview to 'see' that only these nodes have the pressure scalar values and make the correct color interpolation? Thank you very much. Theofilos Manitaras
