CST STUDIO SUITE offers a wide variety of different solvers and solver types. Solvers from different problem types have different demands. They will need different sources, different post processing features, different material properties and so on.

To reduce the number of visible controls and to show only  those you really need, it is possible to select a "Problem Type".

Home: Simulation Problem Type

Selecting this ribbon control offers the following choices:

If one of these items is selected, the program will configure itself such that only those controls are shown that are needed for the selected problem type. The status bar always shows the name of the currently selected problem type.

Besides the changes in the user interface, some internal settings may change as well:

Material

If there are multiple material sets for one material, the one associated with the chosen problem will be activated. With this the appearance of the material in the navigation tree and the material information shown in the mainframe may change as well.

Mesh

Different problem types require different mesh densities and different mesh creation strategies. Currently there are three different strategies:

Coupled Simulations

Changing problem types is especially necessary when doing coupled simulations. For these kinds of simulations different problem types need to be solved for one spatial model. You will need to set up different problem types and run different solvers sequentially.  

High Frequency - Static Thermal

These simulations take a loss distribution or surface currents from a high frequency simulation and use these results as  thermal sources. The thermal solver than calculates the temperature distribution within the calculation domain. -> How to Setup a Coupled HF - Thermal Simulation

Magnetostatic - High Frequency (biased ferrites)

The high frequency material properties of a ferrite material depend on a biasing magnetic field. This magnetic field can be simulated prior to solving the high frequency problem automatically. -> How to Setup a Coupled Simulation for Biased Ferrites
