Is it possible to use 1st order scheme in the LES simulation

Post by MartianDuan »

Dear developer and users,

It there any possible to make the LES run with the 2nd order scheme in code sature?

I am using the Code_saturne 3.0.3 to run LES simulation on the supercriitcal fluids flow case. I came across very strong numerical instability. In stand of decrease the time step. several colleague suggeste me to use the 1st order scheme first.

I tried this idea, however code_saturne killed the case because the accuracy scheme is not the 2nd order. Can you please give me some suggestions?

Thanks in advance,

Yu.
