Create a pressure penetration (Abaqus)

1. Choose Home tab→Loads and Conditions group→Simulation Object Type→Pressure Penetration .

2. In the Pressure Penetration dialog box, in the Exposed Master Surface group, click Select Object , and select the nodes on the master surface that are exposed to fluid. For axisymmetric models, specify one node. For three-dimensional models, specify any number of nodes. You can also specify no nodes. Specifying no nodes is required if the master surface is a rigid surface.

3. In the Exposed Slave Surface group, click Select Object , and select the nodes on the slave surface that are exposed to fluid. For axisymmetric models, specify one node. For three-dimensional models, specify any number of nodes. You can also specify no nodes.

4. In the Contacting Master Surface group, from the Master Surface list, select the surface region, or click Create Region to create a new surface region.

5. In the Contacting Slave Surface group, from the Slave Surface list, select the surface region, or click Create Region to create a new surface region.

6. From the Wetted Front list, select how the fluid pressure loading is applied:NODE — Applies fluid pressure loading to the wetted region until the front penetrated node.MID-ELEMENT — Ramps fluid pressure loading down and applies it to the unwetted front element region beyond the front penetrated node.

7. In the Penetration Time box, type the time it takes for the fluid pressure on the penetrated contact surfaces to reach the current magnitude.

8. In the Fluid Pressure box, type the fluid pressure magnitude. You can use a field to define the variation of the pressure.

9. In the Critical Contact Pressure box, type the critical contact pressure below which fluid penetration starts to occur. The higher the value, the easier the fluid penetrates. A value of zero indicates that fluid penetration occurs only if contact is lost.

10. Click OK.
