I am trying to make a reaction-diffusion model on a growing cylinder.

When I choose 3D model with General Form PDE and Moving Mesh, I can create a cylindrical surface but it does not appear as a "domain" in the Moving Mesh --> Free Deformation options.

Attached is very simple example.

I see that Moving Mesh works in strictly 2D domains (when starting with a 2D model) and also with fully volumetric 3D domains (when starting with a 3D model). Is there a way to using Moving Mesh on a 2D domain embedded in three space?

If not, what is the best alternative? Must I create a "thin" shell that still has non-zero volume and run that mesh? This leads to problems with very small meshing lengths along the "thin" direction.

Other ideas?

Thanks in advance for any suggestions!
John
