how to get the coordinates of nodes on the specific surface in PyMechanical

[GordonGu1998]

📝 Description of the example

Hi, there. My project requires me to apply the pressure field onto the surface of a 3D geometry body. The pressure field is a function of node coordinates (x, y, z). My requests are listed below:

1. Read the mesh node coordinates at the target surface. The face is named 'Face_1' in the named selection.
2. Apply the pressure to the nodes on the target surface. My function will calculate the pressure based on node coordinates.

📁 Files needed for running the example

The request is for general purposes. Any 3D geometry can work.
