plot residuals
Hi, I'm a new user of openfam. I'm running a laminar stady-state case with simpleFoam. I have found on this forum a usefull way to plot the residuals using gnuplot during the simulation and it works. My question is maybe quite stupid.I run a simulation for a certain number of iteration (for instance 400):
simpleFoam >log monitoring the residuals. Now if i have to run again for other iterations ( with the latestTime entry in controlDict ) because my residuals aren't already converged or i have changed something in fvShemes directory if i write again simpleFoam >log my file log at the end of the iterations will contain only informations about iterations from 400 to the final one and also the residuals i plot are referred to those iteration. I wanna know if there is a way to write the new residuals in the same log file i have already in my directory leaving unalterated in it the previuos informations abuot the residuals of the previous run. In this way my gnuplot will show the residuals from the first step. I know i could use a different name (>log1) and then copy it in the previous one but I suspect that a smartest way may exist. thanks |
hello pigna,
use >> instead of > so : simpleFoam >>log then the output will be appended. Hope this helps Wouter |
Thank you, it is exactly the tip i needed .
