Operating Modes
There are two Creo Simulate modes available. The product you select decides the mode you work in. The mode you use governs how you apply modeling entities, the modeling functions available to you, and the types of analyses you can perform. The following modes are available:
Creo Simulate Integrated—Incorporates Creo Simulate functionality into Creo Parametric. In integrated mode, you create, analyze, and optimize simulation models within Creo Parametric. Because you never start the Creo Simulate user interface separately, integrated mode eliminates the need to manually switch back and forth between Creo Parametric and Creo Simulate. Thus, integrated mode represents the most streamlined approach to part or assembly modeling and optimization.
Creo Simulate Standalone—Incorporates a fully functional standalone application for 3D models. You can use, analyze and optimize models created in Creo Parametric or other CAD systems using Creo Simulate standalone. To work in this mode you need only a Creo Simulate license.
In both integrated mode and standalone mode you can work in structure or thermal mode.
The following figure shows the modes and the different submodes available
The following features are common to both integrated and standalone modes:
You can choose whether to define your model for use in native mode or FEM mode. Native mode provides p-element solutions and FEM mode lets you solve your model using any of several third-party h-element solvers.
When working in native mode ,Creo Simulate creates the mesh automatically as part of your analysis. For solid models, Creo Simulate uses solid elements such as tetrahedrons, wedges, or bricks while, for shell models, it applies both triangle and quadrilateral shell elements to achieve the best mesh. You can also have models that combine solid and shell elements to create a mixed mesh.
As an option, you can manually add several specialized element types, or idealizations and connections, to your model. These include beams, various types of welds, springs, contacts, rigid links, and masses.
Although native mode does not normally display elements except as a background for study or analysis results, you can test and refine your mesh before you run an analysis.
You can perform “what-if” studies to better understand your design by varying the dimensions and properties of your model during sensitivity design studies. You can also improve your design by performing optimization design studies that attain a goal while respecting given design constraints.
You can work in more than one model at a time. When you wish to work on another model, you simply open it, and a new work area window opens displaying the newly-chosen model. For more information, see Considerations for Multiple Model Sessions.
Creo Simulate submodes—Within both integrated and standalone you can work in either of the following two modes depending on your modeling needs:
Native mode—Enables you to run integrated and standalone mode using Creo Simulate's adaptive p-code functionality. Native mode lets you create modeling entities like loads, constraints, idealizations, connections, properties, and measures. In this mode, Creo Simulate meshes your model with p-code elements and uses its own adaptive solvers to find a solution.
FEM mode—Enables you to run integrated and standalone mode using Creo Simulate's finite element modeling functionality instead of its p-code functionality. This functionality enables you to create modeling entities like loads, constraints, and idealizations. It also enables you to mesh your model with h-code elements, run your analyses using various finite element solvers including NASTRAN and ANSYS and review the results of the run. You can activate FEM mode by selecting the FEM Mode check box on the Model Setup dialog box in either structure or thermal mode.
Native mode and FEM mode share modeling entities. That is, nearly every modeling entity that you create while in native mode will be active while you are in FEM mode, and vice versa.
Throughout the Online Help both Creo Simulate integrated and Creo Simulate standalone are referred to by the generic name Creo Simulate where the functionality is the same. For special cases where the functionality is different the special case is explicitly mentioned.
