gi_scale_vec for each direction

Question

Is there yet a way to scale conductivities anisotropically on a per-element basis using the gi_scale_vec input? I was thinking a numelem x 3 .dat file with a conductivity scale for each element for each direction. Such a concept is mentioned in this question, and Aurel mentioned that such an addition would be feasible.

No, currently this is not possible.

To integrate this feature, it'll be best to open a Feature Request issue to discuss and coordinate this effort there between you, any contributor and potentially a core developer: https://git.opencarp.org/openCARP/openCARP/-/issues/?label_name%5B%5D=Feature%20Request

After a quick look, the input file reading is triggered here: https://git.opencarp.org/openCARP/openCARP/-/blob/master/physics/electrics.cc?ref_type=heads#L170

the actual reading is done by this function: https://git.opencarp.org/openCARP/openCARP/-/blob/master/fem/slimfem/src/SF_parallel_utils.h?ref_type=heads#L362

Options could be to either read 3 values per element (gi_l, gi_t, gi_n) or to have one file per conductivity direction.

In the latter case, new input parameters would need to be added to https://git.opencarp.org/openCARP/openCARP/-/blob/master/simulator/openCARP.prm?ref_type=heads
