Fluid pressure penetration (Simcenter Samcef)

Fluid Pressure Penetration loads can simulate surrounding fluid or air penetrating into contact interfaces.

To use the Fluid Pressure Penetration load, you must define the following:

• The Possible Wet Zone regions (1) (2) that limit the pressurized areas (4).

• The Contact Selection that lists all the contacts (3) that prevent or allow fluid to pass throughout.In Structural analyses, you can select Surface-to-Surface Contact or Nodes-to-Surface contacts.In Axisymmetric and Other 2D Structural analyses, you select Edge-to-Edge Contact or Nodes-to-Edge contact.

• The Fluid Pressure Loading value and some specific Parameters.

By default, from the faces/edges of the Possible Wet Zone regions, the software automatically detects the pressurized areas. However, in some complicated configurations, you can use the Fluid Penetration Starting Points (5) to define at least one node for each independent area that can be wet, which helps the software to compute the pressurized areas.

Note:

You cannot select any specific results related to the fluid pressure penetration solve. The software automatically outputs the computed Pressure-Element Nodal result (Simcenter Samcef 1322 result code).

Ancillary display

You can use the ancillary display to show the Fluid Pressure Penetration load and to help you check the Possible Wet Zone you selected.

Wet zone

Whether you explicitly select Fluid Penetration Starting Points (1), the Ancillary Display also helps you to check your model, showing nodes that are not reached (2).

In this configuration, the software fails to compute pressurized areas.

You must then correct the data of your Fluid Pressure Penetration load to obtain a valid model.
