# How to analyze a pipe for internal pressure

<Note>
  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.

## 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.](https://files.learn.ntop.com/help-articles/structures/48241353771027.png)

2. \*\*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.](https://files.learn.ntop.com/help-articles/structures/48241337578259.png)

3. **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.](https://files.learn.ntop.com/help-articles/structures/48241353780755.png)

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.
