Reply To: How to apply a heat flux which depends on the Z axis ?

[ErKo]

You are welcome - first we need to have/create a named selection (say of a face) in mechanical where we want to apply the flux, and that I called HFBC.

Once we have that we can use : CMSEL,S,HFBC,NODE, to select all the nodes on that face.

later in the SF command we use all, which apply to all nodes selected by the cmsel command.

All the best
