One moire question,how could I get ∂A(θ)/∂θx,because I did not find any
information about density vector like θ=[θ1,θ2,...,θm],may I know if I have
to set density vector value in this finite element?
Lance -- I have no idea. I don't know the program, but looking at it, I see no
mention of the word "density" anywhere. Apparently, the person who wrote the
program implemented an equation in which density does not appear. If you want
that the density is part of the formulation, you should first write down what
the specific problem is you want to solve. We can't know what it is you want
to do. You should then compare what you want to do with what the existing
program does, and change it so that it matches to what you want it to do.
