Updating, from the Physical or Logical Model, a Generated Modelica Model of a Kinematic Mechanism or an Engineering Model

When the physical or logical data involved in a mechanism generating a Modelica model is modified, you can update the generated model the following ways:

The model generation command
The dedicated command Update Current Model from Physical Model
Any of the generic PLM update commands

This task shows you how to:

Update Using the Model Generation Command
Update Using the Update Current Model from Physical Model Command
Update Using the Generic Update Commands

Update Using the Model Generation Command

You can update the generated model using the model generation command.

Activate the generated model to be updated from the physical or logical model.

Note: You don´t have to open the physical or logical model. It opens automatically when you perform the following command.
Depending on what model to update, perform any of the commands:
- For a mechanism of a physical product, from the Behavior Tools section of the action bar, click Generate from Kinematic .
- For an engineering model, from the Behavior Tools section of the action bar, click Generate from Engineering Model .
  Note:
  An engineering model can be any of:
  - A 3D piping model.
  - A 3D HVAC model.
  - A schematic P&ID model. This is a logical model, but it can be linked to physical objects.
The dialog for the model generation appears, prefilled with the same settings as the ones used for generating the model.
Click OK.
The model is regenerated, and automatically updated from the physical or logical model.

Update Using the Update Current Model from Physical Model Command

You can update the generated model using the command Update Current Model from Physical Model .

From the Behavior Tools section of the action bar, click Update Current Model from Physical Model

The properties of the mechanical model are recomputed, and the Modelica code of the model is regenerated. For an engineering model, the Modelica model is generated using the mapping used for the initial model generation.

Tip: This command works independently of the locking of generated classes. You don´t have to unlock any classes.

Note: For a kinematic mechanism, the following applies:

The root physical model is set to authoring mode to retrieve some data from that model.
If you have already loaded the physical product in the session, for example, you have opened it in a tab, only the relevant parts are loaded, not the full product, to not alter any filtering you have done. If the product is not in the session, the full product is loaded.

Update Using the Generic Update Commands

You can update the generated model using any of the generic commands Update or Update Assistant.

Important: To be able to perform an update of the generated model, three conditions must apply:

The model must have been generated with the option Rebuild at PLMUpdate activated.
(There must be no annotation __Dymola_ModelicaGenerated.rebuildDuringUpdate=false in the locked internally generated model. This setting is for advanced users only.)
Any of the following must be valid:
- The PLM structure of the physical model is modified.
- The physical model is modified, and the modified model has been saved.
- For a kinematic mechanism, the weight definition is modified.

Perform an update with or without the update assistant.

To update without the update assistant, from the standard area of the action bar, click Update .
To update with the update assistant, from the standard area of the action bar, click Update Assistant .

For more information about the update command and the update assistant command, see Assembly Design User´s Guide: Update.

The properties of the physical product are recomputed, and the Modelica code of the model is regenerated.

Tip: These commands work independently of the locking of generated classes. You don´t have to unlock any classes.

Notes:

The root physical model containing the mechanism is set to authoring mode to retrieve some data from that model.
If you have already loaded the physical product in the session, for example, you have opened it in a tab, only the relevant parts are loaded, not the full product, to not alter any filtering you have done. If the product is not in the session, the full product is loaded.
