Creating a Point source in 3-5a

Please login with a confirmed email address before reporting spam

I am trying to do a tutorial meant for a later version of COMSOL on 3-5a. It is using the Helmholtz PDE

The tutorial can be found at www.atomic.physics.lu.se/fileadmin/atomfysik/Biophotonics/Education/MultiphysicsExercise.pdf

The part I am stuck at is 5.2.2.4 Helmholtz Equation (hzeq) ->Assign a point source

"A light source is needed and we have mentioned before that the point placed
in the [material] should be for this purpose. Right click the PDE (hzeq) menu item and then Points >
Point Source.

- Point selection: In the drawing window mark the point using the mouse so that it changes
color. In the Point selection tab click the ”plus sign”. A number will then appear in the point
selection tab, e.g. 5 but the numbering depends on how the coordinate system is defined.

- Source term: Assign a value in [W], e.g. f=0.1 for 100 mW.

The physics parameters are all set, now we need to create the mesh. "

If anyone could help me translate this part to a 3.5a instruction it would be very helpful.
