I use Matlab PDE toolbox and I get this error in my code. How can I fix this error?

"Error using pde.PDEModel/geometryFromEdges (line 46) Assemblies of more than one geometric model are not currently supported."

If you wish to combine two sets of edges then do that before calling geometryFromEdges. If you want to replace an existing geometry with a new one then delete the existing geometry first and then call geometryFromEdges. You can delete the existing geometry as follows:

pdem = createpde
g = @squareg
geometryFromEdges(pdem,g)
delete(pdem.Geometry)
pdem.Geometry = []
% Now you can call geometryFromEdges again
geometryFromEdges(pdem,g)
