请教OF的问题

ivanyao

我是一名初学者。请问各位of的学习者：在of里如何得到网格的精度和数量？如何确定计算的终止时间和时间步？如何得到残差的曲线？因为我想判断解的收敛性。谢谢

Hi

1)try checkMesh utility to get the information of your mesh.
2)you can define the timestep infomation in control dicitionary. turn U-104 in User`s Guide in section 4.3
3)during the solver executing,it reports the status of equation solution to standard output(i.e. screen) you should redirect the to a log file.and use tail command to monitor the log file during iteration,and also can use the foamLog script to extract data in a sets of files.this file could be import to MS EXCELL,Matlab or GNU PLOT  to plot the graph.you can find more in U168 of User `s Guide
