To define time dependent loads (Pressure, Force and Enforced Constraints) for a Non-linear transient solution, you must specify the Time dependent magnitude table into the corresponding load.

Below are the steps to create a time dependent pressure load:

       1. Open the Pressure tool in Analysis > Loads and Constraints > Constraints.

       2. Click on the Create option under Time dependent load magnitude to create the time dependent magnitude table for the pressure load.
