Accessing a pre-existing model node from MATLAB

Hello!

I have created a model using the Comsol interface which automatically generates a geometry node (by default, "Geometry 1"). Using MATLAB I wish to add the entity c1 (see below) to the "Geometry 1" node but I receive the following error message: "Undefined variable "geom1" or class "geom1.feature.create"."

My code is:

model.component('comp1').geom('geom1').lengthUnit('mm');

c1 = geom1.feature.create('c1','Circle'); c1.set('r',Ro); c1.set('pos',[0 0]);

Thank you in advance.

Hi André

You can either do

c1 = Model.geom('geom1').feature.create('c1','Circle'); c1.set('r',Ro); c1.set('pos',[0 0]);

or

geom1 = Model.geom('geom1'); c1 = geom1.feature.create('c1','Circle'); c1.set('r',Ro); c1.set('pos',[0 0]);
