Importing and using FMU

Getting started

The import workflow at a glance

Importing an FMU of any type is made simple by the help of the FMU Import Assistant. Once imported, an FMU behaves as an ordinary Simcenter Amesim submodel:

Procedure

  1. Use the FMU Import Assistant to select the FMU, create and compile an import submodel;

  2. Drop the import submodel on the sketch, connect it to other components;

  3. Change the parameters if necessary (including the step size for co-simulation), run simulation, and post-process the result variables.

Overview of the FMU Import Assistant

The FMU Import Assistant is started from the Interfaces > FMU import assistant menu (see figure below).

The assistant first asks for an FMU and a directory to store the import submodel (see figure below).

It then asks for a C compiler (see figure below). The Generate> button starts the import of the FMU.

The FMU is then imported and the import submodel is compiled (see figure below).

The import submodel is ready to be connected (see figure below).
