| Summary | 0002420: Residuals vary for different writeIntervalls | ||||
| Description | Hello, I noticed a strange behaviour this case. As you can see in the added Zip-folder, the residual-convergence has a dependency on the writeInterval. The two images (gnuplot_residuals_*) show the convergence for a writeIntervall of 1.5s/2s. Depending on the writeIntervall in the controlDict there are four bumps every e.g. 1.5s/2s before it converges. the results are correct, but still it's a little bug.. | ||||
| Steps To Reproduce | run ./continue-parallel | ||||

If you are running with adjustable time-step and writeControl adjustableRunTime; the time-step is adjusted by the write interval which affects the residuals and convergence. To avoid this you could run with a fixed time-step but you have to ensure it is small enough for stability. |
