chemical reaction

Hi Olav,

I'm writing to inquire whether JutulDarcy currently supports chemical reactions and geomechanical processes? Thanks.

Best regrads,

Another thing is that whether it's possible to set the relative permeability coefficient as a constant value, rather than assigning a different coefficient to each grid cell, as shown here:

prm_res[:NonWettingKrExponent][is1] .= 1.8

In this case, the gradient for the relative permeability coefficient would result in a large matrix. However, I want to have a single gradient for the relative permeability coefficient since the coefficient is the same for all grid cells.

Hi! There is no geomechanics or chemical reactions at the moment. Geomechanics does not seem unlikely to add in the future. For chemical reactions, there are many options, but I do not know of any native Julia codes for e.g. surface chemistry.

For your second question, the optimization interface includes lumping of variables. There is also a new high-level differentiation interface that can do this for you: https://sintefmath.github.io/JutulDarcy.jl/dev/examples/workflow/fully_differentiable_geothermal

That's great, thanks for the suggestions!
