absolute pressure limited to 1.0
 

Hi all,

I'm simulating the combustion in a Wankel engine (unsteady model, dynamic mesh, fuel injection, combustion from a pdf file...) and my simulation crashes! The error message I get in the *.out file is:

absolute pressure limited to 1.000000e+00 in 6347 cells Warning: An error or interrupt occurred while reading the journal file. Some commands may not have been completed.

ok, I looked for the settings in Solve/Controls/Limits, where the absolute pressure is of course limited to 1. I should never obtain such lower values, wherefrom could the problems come? Underrelaxation factors or something else?

Thank you a lot! Stéphane
