| Summary | 0000581: 2.1.x chemistry->correct() significiantly slower | ||||
| Description | With the new implementation of the chemistry time advancement there is a significant slow down. In a test, it appears that the chemistry->correct() stage in reactingFoam is approx. 10 times slower than the #include chemistry.H in 2.0.x, though it appears that they perform essentially the same work. Settings for ode solver and other were identical. | ||||
| Steps To Reproduce | In 2.1.x-06e2b3354a6c $FOAM_TUTORIALS/combustion/reactingFoam/ras/counterFlowFlame2D, change the resolution of mesh 10 times in both directions. Run with reactingFoam. First time step ~200 s on my machine. Repeat in 2.0.x-03233a7696f0, with corresponding tutorial, resolution, and solver. First time step ~20 s on same machine. | ||||
