About Creating Models in Creo Simulate

Before you can analyze a part or assembly in Creo Simulate, you must create a simulation model that captures the real world conditions that the model will undergo and such characteristics as the material, the presence of masses, and so forth. You create a simulation model by adding modeling entities that define the nature of the model. In addition, you can evaluate and refine meshes as part of the model creation process.

The modeling entities that you can use to define a simulation model include:

• model type—Indicate whether you want Creo Simulate to treat your model as a 3D model or any of several 2D model types.

• simulation features—Add datum geometry to your model, select and create coordinate systems, and add surface or volume regions.

• idealizations—Define idealized representations of your model or portions of your model to more accurately represent your model to the solver and improve solver efficiency.

• connections—Indicate how areas of your model connect and how loads should transfer.

• constraints and loads for Structure — Add the loads that affect your model and constrain the model's motion.

• prescribed temperatures, convection conditions, and heat loads for Thermal—Subject your model to heat loads and define the boundary conditions that describe the model's thermal environment.

• materials—Define the material that your model is made of.

• material orientations—Describe how orthotropic and transversely isotropic materials are oriented on your model.

• properties—Define the properties of the idealizations in your model, such as spring properties, shell properties, beam properties, and so on.

• measures—Define specific result quantities that you want to measure at specific locations during an analysis. You can define some measures for the entire model, some for specific areas of interest, and some for both.

• AutoGEM meshes (native mode)—Create a mesh of geometric elements for your native mode model, determine whether the mesh is adequate for your analysis, and refine the mesh if necessary.

• FEM meshes (FEM mode)—Create and evaluate a mesh for your FEM mode model and refine the mesh if necessary.
