tips to speedup the convergence of CHT problem with gravity

derisala · February 24, 2011, 00:04

Hello all,

i am simulating the conjugate heat transfer problem with gravity, 1st i got good convergence with only flow , now i am solving flow with gravity ,But its taking much time to get convergence ...

please can anybody give some tips to converge my solution quickly

If your residuals are following a predictable trend and the are reaching the convergence criterion without oscillating too much, a general piece of advice would be to increase the under-relaxation factors to speed up the convergence.
