Assign Loads and Contrains Window

Loads and constraints can either be assigned by solution commands or in a graphical way using the loads and constraints window.

Loads and constraints window consists of sub-windows which are used to assign mechanical, electrical and fluidic loads or constraints. The fourth sub-window provides a summary and can be used to read or write load cases from or to files.

Mechanical domain⚓︎

The mechanical domain sub-window covers the LOAD, ACEL, OMEG and DRIV command features. The following figure shows a pulse force signal in y-direction at rigid body #1. Click on the Add (+) button to assign the specified command. Individual commands can be erased by the Delete selection (-) button and all defined mechanical loads and constraints are erased by the Delete Table button.

Electrical domain⚓︎

The electrical domain sub-window covers the COND, VSCR and ISCR command features. In a first step, conductor port names are assigned to the comb cells and plate capacitances. Existing comb and plate capacitance labels from the model file appear automatically. The conductor port names are defined by users. Click on Add (+) to link the capacitance to conductor ports.

In a second step, different voltage or current sources can be assigned to the conductor ports.

Fluidic domain⚓︎

The fluidic domain sub-window covers the CDMP, RDMP and MDMP command features. The following figure illustrates the assignment of different modal damping ratios. Click on Add (+) to activate the commands.

Import and export of load cases⚓︎

The last sub-window shows a summary of all assigned loads and constrains. The currently defined load case can be exported to a file. The Import from File button is used to retrieve existing load cases. The file content can be added by other solution commands such as MOPT, DCSW, HARF, TIME to assign solver settings.
