visualize OF using Matlab
 
hi there,

I got the openfoam results of the three dimensional fields. Now I would like to make a planar slice of it and then visualize the 2D slice using matlab. Does anybody know how to realize it? I know matlab may only handle the slice data of structured meshes, however in openfoam as you know the meshes are unstructured. Anybody know how to do it properly? Thank you all.

Use the "sample" tool to get data on a slice (in ASCII format). If you have problems plotting that data in MATLAB directly, you can interpolate it to a structured grid using builtin MATLAB functions.

Thank you! If I generate the structured mesh for openfoam, I found that I have to output the mesh as an unstructured mesh. So when I output the 'structured mesh', actually the results are still UNSTRUCTURED. I found that this is a little complex. Thanks.
