Integration steps greater than maximum!!!
Hello everybody
I am simulating a heptane combustion via sprayFoam (OF 5.x) Can anyone tell me what's this error for? --> FOAM FATAL ERROR: Integration steps greater than maximum 10000xStart = 0, xEnd = 5.53853e-08, x = 4.02297e-08, dxDid = 2.29093e-12 From function virtual void Foam::ODESolver::solve(Foam::scalar, Foam::scalar, Foam::scalarField&, Foam::scalar&) constin file ODESolvers/ODESolver/ODESolver.C at line 191. FOAM exiting I get this error at time=0.0008 s then I stopped the simulation and just rerun the simulation, it continued till time=0.00108 then again I get the same error!:confused: |
No body knows about this error?!

And between which models did you change? |

I changed it from seulex to Rosenbrock34. |
Thanks for the suggestion - I'll give that a try. Could also try rhodas...

However, I start with seulex_LAPACK. Then I tried all the ODESolvers including Euler, EulerSI, RKCK45, RKDP45, RKF45, Rosenbrock12, 23, 34, SIBS, Trapezoid, rodas23, rodas34, selux. All failed. I am running the SandiaD_LTS case from the tutorial but changing the reaction mechanism to JL4 and using ode_pyJac as the ode solver. Still can't figure out why! Maybe it's due to the ode_pyJac from DLBFoam. Any suggestions? |
Can also add
solver Euler; absTol 1e-8; relTol 0.1; Not sure if that info still helps |
