FEM ConstraintInitialPressure
Description
Creates an initial pressure condition for a fluid flow analysis.
Usage
- Press the
Initial pressure condition button or select the menu Model → Fluid boundary conditions → Initial pressure condition. - Enter an initial pressure value.
- For a 3D analysis, select a \'solid\' (body) from your model, for a 2D analysis select a face.
Notes
For simple analyses, it is not necessary to specify the initial pressure, however also in these cases it is recommended as best practice.
