laminarSMOKE-flamelet

CFD solver for laminar flows based on OpenFOAM and flamelets

Supported OpenFOAM versions

• OpenFOAM-2.x
• OpenFOAM-4.x
• OpenFOAM-dev

Compulsory libraries

• Eigen (http://eigen.tuxfamily.org/index.php?title=Main_Page)

Optional libraries

• Intel MKL (https://software.intel.com/en-us/intel-mkl)

Compilation

Two different options are available to compile the code

1. Minimalist: no external Intel MKL libraries are needed
2. Minimalist + Intel MKL: better performances thanks to the linking to the Intel MKL libraries is needed

Instructions to compile the Minimalist version

1. Open the mybashrc.minimalist, select the OpenFOAM version you are working with and update the required paths
2. Type: source mybashrc.minimalist
3. Compile the steady-state solver: from the solver/laminarSimpleSMOKE-flamelet folder type wclean and then wmake
4. Compile the unsteady solver: from the solver/laminarPimpleSMOKE-flamelet folder type wclean and then wmake

Instructions to compile the Minimalist+MKL version

1. Open the mybashrc.minimalist.mklselect the OpenFOAM version you are working with and update the required paths (in particular those pointing to the Intel MKL libraries)
2. Type: source mybashrc.minimalist.mkl
3. Compile the steady-state solver: from the solver/laminarSimpleSMOKE-flamelet folder type wclean and then wmake
4. Compile the unsteady solver: from the solver/laminarPimpleSMOKE-flamelet folder type wclean and then wmake

Run your first case

The folder cases/openfoam-4.x/CounterFlow/Coarse contains a simple test case (counterflow diffusion flame). Obviously, if you are using older versions of OpenFOAM, the corresponding folder is cases/openfoam-2.x/CounterFlow/Coarse.

1. Unsteady simulation: Open the laminarPimpleSMOKE-flamelet folder, build the mesh using the blockMesh utility, and run the case using the laminarPimpleSMOKE-flamelet solver. Even if you are interested in steady state conditions, we strongly suggest to always start with unsteady calculations to create a reasonable first-guess solution for the application of the steady state solver.

2. Steady state simulation: you can now move to the laminarSimpleSMOKE-flamelet folder. Copy the last time folder calculated by the unsteady solver (point 1 above), build the mesh using the blockMesh utility, and run the case using the laminarSimpleSMOKE-flamelet solver. In order to reach the steady state conditions, 5000-6000 iterations are enough.
