Something like this maybe. To put data from 3D mesh into a 2D mesh: x, y = var2D.getMesh().getCellCenters() var2D.setValue(var3D((x, y, cutPlaneZValue * numpy.ones(len(x))), order=1)) To put data from 2D mesh into 3D mesh: var3D.setValue(var2D(var3D.getMesh().getCellCenters()[:2], order=1)) I didn't test the above, but that is how it is advertised to work. -- Daniel Wheeler
