Hello All,
I’m visualising 3 phase grain microstructures generated using dream 3d software.I want to visualise the 3 phases and their distribution in the imported .xdmf file which I’m opening with PV 4.2.
As can be seen, I’m shown a monochromatic black colour in spite of the expected distribution. Please help in changing the settings fro the above-attached image so that I visualise many different microstructures.
TIA.
Regards

Please check the “Map Scalars” checkbox in the properties panel. This should fix all your issues.
