Basic simulation and plotting features

Once a Modelica model has been translated, it can be used for simulation like any other Simcenter Amesim submodel. In particular, you can post-process it as you would any other Simcenter Amesim model. For example, with the integrator model used throughout this section, you can select the Modelica component to see the parameters and variables it contains. All the variables from your Modelica model are available for post-processing, including some additional variables introduced during the translation process (e.g., “der(x)” in this case). Simply select the parameter or variable of interest and drag it onto the Simcenter Amesim sketch to make a plot (see figure below).

Note that parameters from your Modelica model may also appear in Parameters menu, allowing you to change their value and re-run the simulation. For example, you could change the parameter v from 1 to 2 and observe the changes in the Integrator model (see figure below).

Note that in some cases, parameters will not be accessible, e.g., because they are inlined during translation or because they are structural parameters whose values cannot change after translation. See Constructing the initialization problem  for more information. Parameters and variables from a Modelica component will appear in a hierarchical list. If your model contains variables at the root level, they will appear in the root level of Simcenter Amesim. If your model contains components which contain variables, then those variables will appear within a folder with the component’s name. For example, the graphical integrator model created in Assembling a Modelica model graphically  contains a list of variables grouped by the names of the components in which they are defined (see figure below). If the components themselves are comprised of other components, the list will have additional layers of hierarchy as needed.
