diverge in low courant number
i have set a filling process of a tube.i have set totalPressure and totalTemperature in inlet and tube is closed at other end and flow is compressible.
A shoch should occur that occures but has low resolution and other issue is that this sowewhat simple problem diverges at low courants like .1 with printstack error.but in higher cfl's like .6 doesn't occure an error but continuity residuals goes far away zero in minus direction when the shocks hits to wall and residuals after that return back to zero again. What may be the cause of this strange behaviour? |
