Haugen Natalia Babkovskaia Added: 01-Dec-2008 Status: Recommended resolution: 1x1x1 (zero-dimensional run) Comments: In this test we solve the energy, density and species equations. The mixture is initially set to a temperature above the ignition temperature, and we follow the ignintion of the mixture. Since the required timestep is not straight forward to determine when chemical reactions are involved we use the Runge-Kutta-Fehlberg method for the timestepping.
