hi
i am new to the openfoam, iwant to simulate the reactive flows in a catalytic convertor . i think the reactingFoam suits the best for my simulation. but iam not able to set the convergence criteria. can anybody help in this issue |

1) when you use a solver for example icoFoam, the residuals will be written in terminal
but first you should redirect it into .txt file then use the command "foamlog" to extract the residual in separate files in logs folder. then use a plot software for example gnuplot to plot the residual, Code:
icoFoam > log foamLog log cd logs gnuplot plot "./....." |

in the fvSolution how can we set the convergence criteria. is it by setting the residual controls?
