how to access co-ordinates of mesh nodes

I am using the transient heat diffusion module. The thermal conductivity of one of the sub-domains in the geometry is a user defined function in Matlab and depends on the co-ordinates of the mesh nodes. When I call this function in COMSOL I pass x and y values to it. However I have found that the values as well as the size of x and y change over time (i.e. from time t=0 to tome t=tfinal) and also that these x and y values do not represent the mesh nodes. How can I access the mesh nodes? Are the variables named differently? Please help.

Thank you.

You could use xmeshinfo. If you run xmeshinfo(fem,'out','dofs'), it will return a structure with information about the extended mesh. The coords field of the structure will have the coordinates for all nodes.
