Well, you can find quite a lot of info about any mesh from within the Model Builder. For example, by going to Component 1, then right-click on Mesh 1, and choose Statistics. This will bring up info about the number of vertices and the various numbers of various types of elements in your mesh, along with various options for displaying/listing their characteristics. I hope that helps.

I you have access to LiveLink for Matlab you can use the function mphmeshstats to retrieve the coordinates and connectivity for all the mesh types you have in the mesh.

Dr Gregersen, how about the syntax when there are multiple meshes?

help mphmeshstats gives you the answer.

E.g. stats = mphmeshstats(model, 'mesh2')

If you write stats = mphmeshstats(model, and press TAB then Matlab will show you the valid mesh tags
