Creating a Physics Interface or a Multiphysics Interface

Creating a Physics Interface or a Multiphysics Interface

These steps outline how to build a new physics interface with the Physics Builder:

1

Define the physics by formulating domain equations, domain sources, boundary conditions, and boundary sources, which represent the available nodes in the physics interface. Depending on the physics, equations, conditions, and sources for edges and points can also be added.

2

Identify the physical quantity or quantities to solve for (the dependent variables).

3

List the parameter settings that have to be available for the entire physics interface, which are the parameters that do not depend on the selection of geometric entities (geometric entities are domains, boundaries, edges, or points). Organize similar such parameters in groups representing the properties of the physics interface.

4

Add a new Physics Interface or Multiphysics Interface to the tree.

5

Enter information for the physics interface into the window, initially in the , , and sections.

6

Add the dependent variable declarations for the variables to solve for.

7

Add the features that the physics interface requires. All features can be added directly under the physics interface. Alternatively, add them to (

) and then add a link to the feature in the physics interface. By placing features in the branch (

), these features can be reused by linking from several physics interfaces.

8

Add the properties to the physics interface in the same way as the features.

9

Test the physics interface in some of its supported space dimensions using one of the options on the menu (

) on the toolbar — (

), for example.

This preview automatically sets up a simple modeling environment with a predefined geometry and an instance of the physics interface. Experiment with the window for all features, the GUI logic, and investigate the generated equations in the equation view. To test a physics interface more thoroughly, use The Physics Builder Manager.

Add Study and Solver Defaults, Mesh Defaults, Result Defaults, and Documentation to make the physics interface more intuitive and easier to use.
