Hi all, I want to apply the calculator filter on the results of some 3D numerical simulation but keep getting the following error message (it appears about fourty times in the Ouput Messages window):
ERROR: In /home/berk/Work/ReleaseBuilds/ParaView3/VTK/Graphics/vtkArrayCalculator.cxx, line 305 vtkArrayCalculator (0x882fbf8): Invalid array name: VelSca0 About the data: I have opened a file Conc_Anim.pvd with one float (Conc_0) and another file VelScalar_Anim.pvd with three floats (VelSca0, VelSca1, and VelSca2) for the velocities in x, y, and z direction. To be able to do some calculations with data from both files, I used Group Datasets. The calculation should be something like Conc_0*(VelSca0*iHat+VelSca1*jHat+VelSca2*kHat) though the error message appears whatever I enter as a formula. Does anybody have any idea what went wrong here? Thanks, Michael
