Primerjava CGS in BiCGSTAB(L) v robno-območni integralski metodi /
V prispevku smo primerjali iterativni metodi CGS in BiCGSTAB(L). Zanimala nas je učinkovitost reševanja sistemov linearnih enačb, ki nastanejo pri diskretizaciji Navier - Stokesovih enačb za laminarni tok nestisljive tekočine z robno - območno integralsko metodo. Kot testni primer smo uporabili nara...

| 520 | |a V prispevku smo primerjali iterativni metodi CGS in BiCGSTAB(L). Zanimala nas je učinkovitost reševanja sistemov linearnih enačb, ki nastanejo pri diskretizaciji Navier - Stokesovih enačb za laminarni tok nestisljive tekočine z robno - območno integralsko metodo. Kot testni primer smo uporabili naravno konvekcijo v kotanji. Reševali smo matrike, ki nastanejo pri diskretizaciji prenosne enačbe za temperaturo in za vrtinčnost v prvem koraku nelinearne iteracije. Primerjali smo procesorske čase, števili iteracij in norme vektorja ostankov. Za konec smo izračunali stacionarno stanje pri naravni konvekciji v kotanji za Ra=▫$10^{3}$▫. | ||
| 520 | |a In this paper the comparision of CGS and BiCGSTAB(L) iterative methods have been made. The main interest was in efficient solving of systems of linear equations obtained by discretization of Navier-Stokes using boundary-domain integral method. Tests was performed on the case of natural convection in a cavity. Matrices from discretized transport equation for temperature and worticity in first nonlinear iteration have been solved. Computational times as well as number of iterations and error norms have been compared. In the end the steady state solutions of natural convection in cavity for Ra= ▫$10^{3}$▫ has been compared. | ||
