Converting 1D geometry into 1D-spherical (where Model uses Diffusion and Moving Mesh Modes)

I am working on some reaction kinetics problem (say 1D-spherical catalyst) where i have 5 boundaries (outer boundaries are fixed, two inner boundaries are moving on one side and one on the other).
So, I am using diffusion and moving mesh application modes. I have taken 1D geometry in COMSOL and converted to 1D spherical by adding r^2 terms in subdomain and boundary settings only in diffusion mode in such a way that it exactly represents diffusion equation in 1D spherical system. (carefully referred Spherical Ore example in COMSOL model library).
My question is "do i need to use some correction factor or procedure (similar to which i used in diffusion mode) in Moving mesh mode". If not, then how can moving mesh application mode knows that my geometry is 1D-spherical? I am not getting exact results but those are very very close. That why i am thinking that there might be problem with geometry in moving mesh mode.
Any ideas or suggestions or comments are greatly appreciated...
