Hi Thomas,

There are various ways:

1 You could resample the data on a regular grid and visualize the tensors at those nodes. You can you the CreateLatVol Module to generate a regular sampled mesh with the same bounding box as your data and then you can use either MapFieldDataOntoNodes or MapFieldDataOnElems to map data from one mesh to anothor.

2 You could use clipping to clip a shell or a segment of the data and only visualize those. The ClipFieldByFunction or ClipFieldByMesh modules can help with that.

3 You can as well generate randomly chosen points inside the volume of the TetrahedralMesh and you can use GeneratePointSampllesFromFieldOrWidget and then map the tensors/ vectors onto those nodes with either MapFieldDataOntoNodes or MapFieldDataOnElems.

cheers,

Jeroen

Hello Scirun-Users!

I want to visualize a tensor and a vector field (tetrahedra mesh) with some 100k elements. Both it is too hard for my computer and it would look much better if there where less elements shown. What is the best way to show only a couple of elements?

Thanks in advance
Thomas
