What Are the Best Free 3D Plotters for CFD on Linux?

[minger]

Hey guys, quick question,

I am in a little bit of a bind. I need a 3D plotter to post-proc some CFD runs at home. I have typically used plot3d in the past, but am having trouble getting it to compile on my machine (Ubuntu 10.04). I did a search and there's another program which can handle this called mayavi2. Unfortunately, mayavi2 cannot handle a full multiblock structured grid; it will only show one block of data at a time.

Does anyone know of anything else I might be able to use? Free...preferable.

Thanks,

There is a GNU Plot, and Maxima CAS which are freely available. GNU plot is also integrated with octave, a free matlab-like software.
