I probably just don't know what I am doing, since I didn't ever use COMSOL until last week. Anyway, I have a model that I would like to refine the mesh. However, I can't seem to get this to work. Using
mphmesh(model,'mesh1')
plots my mesh like expected, but
mesh1.feature.create('ref1','Refine');
??? Undefined variable "mesh1" or class "mesh1.feature.create".

What is the deal?

EDIT: I am using COMSOL 4.1 and MatLab 2011a

EDIT: I get the following error when trying to create the mesh (I figured maybe it didn't actually create the struc)

mesh1=model.mesh.create('mesh1','geom1')
??? Java exception occurred:
Exception:
com.comsol.util.exceptions.FlException: An object with the given
name already exists
Messages:
