Quilt Surface

A positive pressure load acts opposite the direction of the surface's normal. The normals for adjacent surfaces may be in opposite directions, although Creo Simulate attempts to align them where possible.

When you create a pressure load, use the Preview button on the Pressure Load dialog box to check the application direction. To reverse the direction, change the sign of the pressure load.

Solid Face

A positive pressure load always points into the solid, unless there is a shell on the face.

2D Solid Edge, 2D Plate Edge, 2D shell

A positive pressure load points into the 2D solid or 2D plate.
