I write here several doubts I have inside the properties modules, please if you can give me a hand with this,
First, I see that there is the possibility of selecting the way of discretization of the advection and diffusion. It can be distinguished between explicit and implicit. What is each for? I´ve seen the values you use in a project, but can you explain which criteria I have to follow to decide between them?
Related to this, once this is decided, I have to set the method. Do you always use the upwind order 1? What is the difference between them?
Then, I see the blocks defining the dispersion/long&trans. This aggregates molecular diffusion and mechanical dispersion, right? And would it be like a cte value with which we delay the transport in the flow direction (long) and in perpendicular direction (transversal) right?
I think is enough for now
