Defining a fluid pressure penetration load

Display the fluid pressure load editor using one of the following methods:

To create a new fluid pressure load, follow the procedure outlined in Creating loads (Category: Mechanical; Types for Selected Step: Fluid pressure penetration).
To edit an existing fluid pressure load using menus or managers, see Editing step-dependent objects. To edit the region to which the load is applied, see Editing the region to which a prescribed condition is applied.

In the Magnitude text field, enter the fluid pressure magnitude (units FL⁻²).

If desired, click the arrow to the right of the Amplitude field, and select the amplitude of your choice from the list that appears.

Alternatively, you can click

to create a new amplitude. (See The Amplitude toolset for more information.)

In the Critical pressure text field, enter the critical pressure.

In the Time period text field, enter the time period.

This field is supported only for Abaqus/Standard analyses (linear perturbation analyses are not supported).

Click the arrow to the right of the Wetting type field, and select the option of your choice from the list that appears:

Select LOCAL to define the algorithm for controlling the evolution region.
Select WETTING ADVANCE to define the algorithm for controlling the evolution region in Abaqus/Explicit analyses.

If you selected WETTING ADVANCE in the Wetting type field, perform the following steps to define the evolution regions in the table.

In the Evolutions region column, double-click the cell of the table or right-click and select Edit region.
Select a region in the viewport.
A default name is provided in the prompt area, but you can enter a new name.
To select from a list of existing sets, do the following:
1. Click Sets on the right side of the prompt area.
2. Select the set or surface of interest, and click Continue.

Click OK to save your data and to exit the editor.
