why continuity doesn't solve when p be fixedGradient in groovyBC?

I have set p in outlet be:
Code:
(internalField(p)-50000) but it seems continuity doesn't solve for that as can be seen in the attached image.why? |
How come that you are not satisfied with 1e-18? I would say it was perfect from a continuity perspective.
Kind regards, Niels |
hi Niels
in first time steps its a straight line without fluctuations.I think maybe it be an issue. |

dear Bernhard.I don't want that residuals to be less than 1e-18 ar such thing.
I focus on time 0 till around time 2e-5 that the continuity is a stright horizontal line.I ask why in this period (in figure) there are not any fluctuations in residuals.is it normal?how and why?! |
I found out why its so!
in first time steps the residuals are of order 0f 1e-22 or 1e-21 and are very low in compare with later times(2e-5 to next)(I don't know the exact reason) then they appear as a line without fliuctuations,in next time steps continuity errors are a bit higher but are low enough as dear Benhard and dear Niels told to say continuity is satisfied. |
