Hell there,
I'm trying to simulate a curved Hydrofoil that is partly submerged in Water. However i can't get the forces acting on the hydrofoil to converge. They start at a very low number (-30k) Newtons, then rise up to around 1300 - 1700 (Which is around the expected value), stay there for a while then go all the way up to insane values like 10^44 Newton. I'm running the simulation in OpenFOAM-2.3.1 using LTSInterFoam. I've tried having the outlet as zeroGradient as well as fixedValue. I've also tried different maxCo values but those still diverged. Does anyone have an idea what other factors i could play around with? One thing i noticed is that when i introduce stream tracers to the results they seem as expected for the submerged and dry areas but the water surface seems very erratic. Would it help to share my config files for the case? If so can someone recommend a good way to do it? Just copy pasting them into this post seems like it would be very tedious for you to look at them. Greetings and thanks in advance Florian |
