CST includes full wave simulator, circuit simulator, particle simulator. Please explain what you want to do using CST cosimulation with matlab in detail. Do you want to use matlab to control CST simulator? As I know, you can use the program based on macro language to control CST, while the matlab can control HFSS by script language.
In general you can use macro language for post-processing in CST MWS. You can open edit window for macro language by pushing the left key of the mouse dragging the mouse up at the bottom of the edit window of CST MWS.
yea, talking about CST, can anyone show me whether it is possible to define a point source as your source port? i can beleive i cannot do a simple simulation with a point source as my excitation.
