Simulations

One or more simulations are maintained within the part or assembly document. Each document can have any number of simulations. The simulation result files, which can be large, are maintained separately and linked to the document unless you specify otherwise.

A simulation contains:

• Simulation Type
• Parameters
• Materials
• Loads
• Constraints
• Contacts
• Mesh

for the purpose of:

• Evaluating the structural loading conditions and frequency.
• Comparing the results of using different materials and parameters.
• Analyzing behavior of different geometric configurations.
• Importing motion loads from Dynamic Simulation.

Note: Inventor creates a set of nested folders and nodes for each simulation.

To examine the performance of a model, replicate the environment the model can experience. Start by building an assembly model containing all pertinent components. Then create simulations for each operating condition to examine.

In setting up a simulation, consider specific questions, such as:

• What is the design objective for this simulation?
• What materials to use?
• Which parts of the geometry can I change?
• What are the underlying physical forces?
• How is model movement constrained?

As you refine a design, analyze the results of the simulation to determine the relationships between the criteria. Then proceed to the next step or iteration of the design.

Simulation Types

• Static Analysis evaluates structural loading conditions.
• Modal Analysis evaluates natural frequency modes, including rigid body movements.
