Post : visualizing/manipulating fields defined on mesh centers


CFD solvers often provide a solution defined on mesh centers. For visualisation of structured grids, Cassiopee provides the C.center2Node function that takes into account the matching connectivity if it is defined in the computational tree:

Similarily, gradients and gradient based computations of variables using P.grad P.computeVariables or P.computeExtraVariables use matching connectivity if defined:
