LTS in new versions of openfoam

mahdi_izadi · December 22, 2018, 20:47

Dear colleagues!
Hi
A solver called LTSInterFoam is illustrated as a steady-state solver based on interFoam solver, which can give a very fast result is som cases
I don't know why, but I can't find it in the latest versions of OF.
Do anybody knows what is the reason for omitting that from the solver list?
Going through the codes there is an 'if (LTS)' loop in the interFoam solver. Is it because if integration of InterFoam and LTSinterfoam? If so, how can I use it?

Yes, LTS functionality has been integrated into the base solver(s) in the newer OF versions. To use it, make your ddt in fvSchemes "localEuler". There will be various parameters you can alter to control the stability of your simulation. These are best explained by examining the associated code : https://github.com/OpenFOAM/OpenFOAM...F/setRDeltaT.H.
