Hello everyone,

I am using Comsol 4.2a and the matlab LiveLinkand I am looking for a way of finding all the dofs on a special entity in matlab.
Here is what I do:

I create a CoefficientForm-PDE and define a Dirichlet Boundary the following way:

model.physics.create('c', 'CoefficientFormPDE', 'geom1');
model.physics('c').feature.create('dir1', 'DirichletBoundary', 1);
model.physics('c').feature('dir1').selection.set([3]);

After meshing and solving I would like to know the coordinates (or the indices) of all the dofs, that lie on this Dirichlet-Boundary! How can I do that?
I have tried mphgetcoords and mphselectcoords but I didn't manage it.

Is there a simple way to get all the doffs?

Thank you very much!
Oli
