Hi everybody,
I am simulating a high energy beam striking surfaces to be joined by welding,and I want to add a specified heat flux to the free surface of a solid with a simple algorithm inserted into the user customizable routine, qsadd.f. But I don't know how can I add a heat flux to every free surface element that lies within a region defined by a "phantom" obstacle in the routine?Could you tell me how to realize it? Thanks.
