Hi Helena,
you saw correctly that this is not implemented so far.
However, this is a relatively straight-forward modification of the
EnergyVolumeVariables
(https://git.iws.uni-stuttgart.de/dumux-repositories/dumux/-/blob/master/dumux/porousmediumflow/nonisothermal/volumevariables.hh)
since
Hi Bernd,
thanks a lot for your help, I am now able to set the conductivity locally
this way.
I am still wondering if it is possible to set the 2x2 conductivity tensor
somehow (also locally), to enable anisotropic upscaled conductivities?
Something similar seems to exist for the permeability
