I am modelling this in ALtair Simlab using 3D magnetostatic analysis.
Problem statement: Extract magnetic fields at 1, 2, 3, 4, 5, 6 mm airgaps from a magnet. I don't want to use existing nodes in the mesh rather I would like to define points using coordinates and extract magnetic fields at those points. I would also like to plot Magnetic fields at these points vs rotation of the magnet about its axis. I can't find any option in the Simlab app for this, there is an option to plot by selecting the nodes in the model but cannot use points defined by coordinates for this.
Model setup - I have a cylindrical magnet and another cylinder to define airgap on top of that magnet cylinder with matching tet mesh for both & infinite box defined around it.
