Boundary Point Probe
Use a Boundary Point Probe () to monitor the development of a scalar-valued quantity (real or complex-valued number) from a dynamic simulation (time-dependent, frequency, parametric). By default a Point Probe Expression subnode is added, or right-click Boundary Point Probe to add additional subnodes.
Boundary Selection
Select a single boundary to add to the Selection.
Point Selection
When working with multiple frames, select a FrameSpatial, Material, Geometry, or Mesh — followed by the coordinate names: typically (x, y, z) or (X, Y, Z) depending on the physics in 3D.
Enter the Coordinates. A red dot indicates the position of the point on the selected surface in the Graphics window. Click the surface to move the point, or enter x, y, and z coordinates. If the point is not on the boundary, the probe location becomes the closest point on the boundary, with coordinates indicated by On surface under the fields.
