Currently ParaView can interpolate the point data loaded from a vtk file onto Gauss points in order to visualize them. That is wonderful.
Most finite element calculations create data at Gauss points directly, such as stress and strain tensor components. Currently ParaView cannot read tensor data directly at the Gauss points of a cell. The lack of this feature in ParaView is a deal breaker in the finite element analysis community.
Please implement this feature.
