[idvusers] unstructured tetrahedral mesh

Hello,
We are interested in using IDV to visualize results from 3D finite element 
models which are arranged on an unstructured tetrahedral mesh.  We can't use 
netCDF to store the results and visualize with IDV because there is no standard 
for unstructured grids in netCDF. 
Has anyone out there used IDV to visualize data arranged on an unstructured 
mesh?
Thanks for any pointers.
