Solver-specific modeling objects

Modeling objects let you specify various settings that determine how the solver processes your model. The types of modeling objects that you can create, and the contexts in which you can create them, vary depending on the solver. You can always create a modeling object using the Modeling Objects command. Depending on the solver, you might also be able to create modeling objects when you create the solution. You can also import a modeling object from one simulation for reuse in another simulation. For more information, see Importing simulation entities.

Each modeling object has a unique numeric label. The software automatically assigns an incrementing number to each modeling object as you create it. However, you might want to use your own numbering paradigm. For example, you might want to use one range of numbers for one solution, and a different range for another. This makes it easier to filter the modeling objects that appear in the Modeling Objects Manager dialog box.

You can typically reuse the same modeling object for different solutions. For example, if your solver is Simcenter Nastran and your model contains multiple solutions, you can create a solution parameters modeling object and reuse it in each solution. Alternatively, you could create multiple solution parameters modeling objects to compare the output from different sets of settings.

Modeling objects are saved with the FEM or Simulation file in which you create them. To save time and ensure consistency, you can store predefined modeling objects in custom FEM or Simulation file templates.

Modeling objects and the Simulation Navigator

After you create a modeling object, it appears under the Modeling Objects container in the Simulation Navigator. If the list becomes extensive, you can filter it to display only modeling objects whose names match a defined wildcard (such as Bulk Data*), or only one or more specific types of modeling objects.

For solutions that display their own modeling object container in the Simulation Navigator (such as SOL 200 Topology Optimization), you can add a modeling object to an active solution or solution step by dragging the object from the Modeling Objects container. You can also right-click a modeling object under that container and choose Add to Active Solution or Step. (The modeling object is added to the active solution step if there is one. Otherwise, it is added to the solution.) When you select a modeling object under the Modeling Objects container, all solutions and their containers that use that object are highlighted. Likewise, when you select a modeling object under a solution or solution step, the corresponding modeling object is highlighted under the Modeling Objects container.
