Question Mesh interpolation

Hey everyone,

I've been diving into the world of bird simulations and hit a bit of turbulence (pun intended!). Started out with your standard unsteady k-omega setup to study our feathered friend in various angles of attack. Got some cool data on pressure, velocity, and vorticity fields all the good stuff.

Then I hit a snag. Needed to solve a special equation (check out the image attached), so I rigged up a new sim. This time I went with Finite Element solid energy, tweaked the material properties, and voila, got the derivatives I was after. Turns out you can't trick the gas domain solver into ignoring the extras we don't need, so I went the solid route.

Now for the tricky part: I've got two sets of solutions on two wildly different meshes and domain types. And I need to merge 'em. Tried to coax Star-CCM+ into doing the heavy lifting, and when that didn't pan out, I attempted exporting the data to CGNS and wrestling with it in MATLAB using cgns4m.

But no dice. So, I'm throwing this out to all you CFD gurus got any magic tricks up your sleeves for interpolating one solution set onto another?

Any tips would be a lifesaver!

Have you tried the volume data mapper? Other than the help file, here's a link to additional instructions:
