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 MeshBoundary Conditions (BCs)

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.
The starting geometry for this workflow example. An imported CAD part of a Pipe is used to extract important faces. The inner pipe face and end faces are extracted as variables. The pipe is also converted to an implicit body.
  1. Meshing: Next, the FE Volume Mesh and FE Domain are created to apply material properties.
The pipe model is converted to an FE Volume Mesh. The FE Solid Domain is then created using the FE Mesh and applied material properties.
  1. Boundary Conditions: To finish the Static Analysis setup we apply the Boundary Conditions and then run the analysis.
Boundary conditions are then applied to the model. For this example, we will apply pressure to the inner face and fix the end faces in place.
  1. Analysis: Using the Deformation scale slider, you can see the effects of the Pressure on the pipe.
A gif showing the static analysis results on the pipe. The pipe model expands as the deformation scale is increased. And that’s it! You’ve successfully setup an internal pressure analysis.
