Hi, I’m plotting the results of my simulation with Paraview. It is a rectangular domain with inside a circle, which represents the flow around a cylinder. When I want to plot the vorticity and I choose a color palette, is there a way to keep the rectangle white and only the flow around the cylinder colored? I mean this is rainbow desaturated palette and I would like to know if there is the possibility to turn that green to white keeping only the colors around the cylinder
Just configure your colormap the way you want it to be. eg set white to the value 0.
… and besides changing the colormap, also set Ambient=1 and Diffuse=0 in the Lighting section of the slice, because otherwise the then white areas are going to look grayish.
