This article uses Simulation/Optimization and both of them in nTop have two requirements: FE Mesh and Boundary Conditions (BCs). Follow the instructions in the links below to prepare your model for simulation.

FE Mesh

• How to create an FE Model

Boundary Conditions (BCs)

• How to choose boundaries of an FE Mesh - FE Boundary by Body
• How to choose boundaries of an FE Mesh - FE Boundary by Body
• How to use Boundary Conditions
• How to use a CAD Face in a boundary condition

Question:

How can I simulate a pipe with internal pressure?

Applies to:

• Simulation

Answer:

1. Setup: The initial setup shows our imported pipe as well as the CAD Faces we've defined.

2. Meshing: Next, the FE Volume Mesh and FE Model are created to apply material properties.

3. Boundary Conditions: To finish the Static Analysis setup we apply the Boundary Conditions and then run the analysis. 

4. Analysis: Using the Deformation scale slider, you can see the effects of the Pressure on the pipe.

And that’s it! You’ve successfully setup an internal pressure analysis.
