Hello

I am trying to visualise large datasets on my cluster using ParaView but I cannot see the mesh. I can see the colourscale of pressure on the side. I am not sure where the error is. These are computationally intensive simulations on spectral element mesh generating (.NEK5000) files. I can see the outline but when I switch to surface, I cannot see anything.

I tried accessing paraview on cluster and remotesystem with high computational power.

Regards  
Pranay

Try changing the representation type. It looks like you’re seeing the outline. For large unstructured datasets, ParaView opts for outline by default.

It’s just that I can see atleast the outline when I use the outline representation and when I switch to surface, I see nothing. I got the solution by cleaning the grid option.

Thanks
