The RF Module Modeling Process
The modeling process has these main steps, which (excluding the first step), correspond to the branches displayed in the Model Builder in the COMSOL Desktop environment.
1
Selecting the appropriate physics interface or predefined multiphysics coupling when adding a physics interface.
2
Defining component parameters and variables in the Definitions branch ().
3
Drawing or importing the component geometry in the Geometry branch ().
4
Assigning material properties to the geometry in the Materials branch ().
5
Setting up the model equations and boundary conditions in the physics interfaces branch.
6
Meshing in the Mesh branch ().
7
Setting up the study and computing the solution in the Study branch ().
8
Analyzing and visualizing the results in the Results branch ().
When using frequency related study steps, define the simulation frequency in the Study branch first. The frequency in the Study node will then be used for defining the physics-controlled mesh and in any frequency-based physics features.
Even after a model is defined, you can edit to input data, equations, boundary conditions, geometry — the equations and boundary conditions are still available through associative geometry — and mesh settings. You can restart the solver, for example, using the existing solution as the initial condition or initial guess. It is also easy to add another physics interface to account for a phenomenon not previously described in a model.
