Matlab again will probably be the only efficient way. You'll see from Comsol m-files that the boundary conditions and subdomain properties are formatted in matrix form (using brackets). Thus, you should be able to define a matrix that contains all of the boundary conditions (i.e. a vector containing the force applied at each boundary), then use that matrix when writing the m-file. I can't give you much more explanation than that as I don't know the nature of the B.C.s that you are setting.

Good luck,

Mike
