I am interested in modelling the speed & pattern of convection within a lake. I have tried to set up a model that includes elements for the ground (fixed temperature, soil), lake (background medium, water), air (fixed temperature, air) and a heat exchanger (fixed temperature, steel). It would be nice to incorporate insolation if possible.
I have a couple of issues:
1) If the air layer is small, all heat dissipates through it. If it is large, the model returns a fatal error.
2) There does not appear to be any horizontal mixing/circulation currents.
Any guidance/advice much appreciated. Is Energy2D suitable for this type of application?
Thanks. Based on your comment I made the lake deeper and more proportional, it seems to be OK with this version. When the model stabilises, it looks as though the soil is heating the water to much higher temperatures than the soil temperature, but perhaps it is just the result of warmer water being forced down the sides?
