The merge introduces a change to the functionality of the VTKOutput class. When writing P2(Vector)Functions the default now is to use VTK_QUADRATIC_TRIANGLE or VTK_QUADRATIC_TETRA as cell type.
The old way to export these functions as P1Functions on a refined mesh is for the moment still supported and can be activated by calling
-
setUseVTKQuadraticTriangle( false )or setUseVTKQuadraticTetra( false )
on the corresponding VTKOutput object.
Comparison of the old versus the new approach looks good so far. In the following figures the left part shows a visualisation with the old and the right with the new approach:
