FEM Mode Workflow
When you analyze a design in FEM mode, you typically complete the following five-step process:
 |
• Create model geometry in Creo Parametric.
• Simplify your model.
• Select or define a system of units.
• Add modeling prerequisites such as coordinate systems and regions, if desired.
• Add materials, loads, and constraints.
• Add idealizations such as shells, springs, beams, and masses.
• Add connections such as welds, links, and interfaces.
• Define the analysis.
|

|
• Select the analysis type.
• Select the constraints, loads, modes, and frequencies to be used in the analysis, as applicable.
|
|
|
||
|
• Apply mesh controls.
• Create the mesh.
• Review the mesh and refine, if necessary.
|
|
|
||
|
• Export the mesh to FEA solvers such as NASTRAN or ANSYS.
• Review the exported mesh.
• Optionally, run the analysis.
|
|
|

|
• If you ran an analysis, you can import the solved model into the postprocessor and review the results.
• View graphical renditions of your model's analysis results
• Define FEA parameters for your results
• Review the analysis statistics
• Evaluate FEM Hard Point reports
|
Be aware that the order of the steps—particularly during the model development phase—may be different depending on your preferences, modeling goals, and techniques. Additionally, if you plan to export a deck rather than run a FEM analysis from within Creo Simulate, you can skip defining an analysis.
You can also consider an alternative workflow if you are working with an assembly and create a hierarchical mesh.
