Dear all,
when modelling an active layer, there is a bunch of issues coming up:
1. piping distance must be equal to or higher than 7 cm --> is there a
way to model 5 cm?
2. the pipes must be embedded in twice the same layer, i.e. the one
above the active layer equals the one below, except for the thickness --)
how can I model a case where the layer above has a very small thickness
(like 1 cm)? There is a limit that is higher than that ... which I assume
has to do with numerical stability ...
3. there is a limit on the thickness for layers ... which I can get.
Only issue than is the modelling of a thin bitumen layer of 2 mm is
impossible --> solution?
Any suggestions on how to solve those?
thanks already
