Dear All,
I tried to calculate the electrical flow through a mesh region,
like \int_{\Gamma} F(x)\cdot n\ d\sigma.
After some trials I found a working way by means of "gf.asm_generic", see the code here below:
Electrical _current = gf.asm_generic(mim, 0, '-sigma*Grad_V.Normal', MeshRegion, 'V', 1, mf, dataV)
Question_1: is this method correct or is there any other way to perform this kind of calculation?
Then, since it is a calculation performed on a Dirichlet region, I wanted to do the same calculation integrating the Lagrange multiplier. I tried the same technique but the result of the integration is NaN, probably because the multiplier variable has less DOF than MeshFem.
Question_2: How can I perform this integration?
Thank you in advance.
Lorenzo
