Hello,
Thanks for implementing getdp/gmsh. It’s a very nice software, very well constructed.
I’m implementing a model similar to the one described by Evgueni Ianenko in this message : http://onelab.info/pipermail/getdp/2005/000670.html
Like Mr Ianenko, I want to complete the total electrical current flowing through a surface.
In his reply, Christophe Gueuzaine explained the process to compute the integral of the normal component of the gradient of the electrical potential on a surface :
"If you need this component in an integral, the solution in getdp is to use a "OnOneSideOf" group with a BF_GradGroupOfNodes basis function.
There is an example here: http://www.geuz.org/getdp/wiki/MagnetoDynamics. You can then use the associated global quantity in post-processing. »
However, the link http://www.geuz.org/getdp/wiki/MagnetoDynamics is not valid anymore. Could you provide a new reference to the demo example ?
Thanks a lot

PS : I made some research before :
- You can find on the OneLab website the description of an electrodynamics problem (http://onelab.info/wiki/Magnetodynamics_with_cohomology_conditions), but it doesn’t use the BF_GradGroupOfNodes basis function.
- Searching BF_GradGroupOfNodes, you find another occurence of the same problem (http://onelab.info/pipermail/getdp/2015/001804.html) but the mentioned demo model Capacitor2D is not visible neither on the web!
