i cant able to decide which solver i should use?
i am simulating flow in rectangular channel with wall temperature in some region. i modified icoFoam solver and added energy quation but some of the post processing tools didnt work like wallShearStress and wallHeatFlux. i dont know what is the probelm, i am getting error Usage: icoTempFoam [OPTIONS] options: -case <dir> specify alternate case directory, default is the cwd -noFunctionObjects do not execute functionObjects -parallel run in parallel -roots <(dir1 .. dirN)> slave root directories for distributed running -srcDoc display source code in browser -doc display application documentation in browser -help print the usage now can i use alternate default solver buoyantBoussinesqPimpleFoam. i dont want to consider buoyancy effect in my simulation and i want to use for laminar flow. Regards, Saurav |

Use buoyantPimpleFoam

You can use buoyantPimpleFoam with gravity turned off and laminar model selected in the turbulence properties.
Check the tutorial case in Code:

buoyantBoussinesqPimpleFoam is used for Transient solver for buoyant, turbulent flow of incompressible fluid. & buoyantPimpleFoam is used for Transient solver for buoyant, turbulent flow of compressible fluids for ventilation and heat-transfer so i think i should use buoyantBoussinesqPimpleFoam for incompressible flow. |

buoyantBoussinesqPimpleFoam is used for Transient solver for buoyant, turbulent flow of incompressible fluid.
can i use it for steady laminar flow, incompressible, without bouyanct force. by using g= 0 m/s^2, model=laminar and deltatime = 1 |

Don't ask the same question twice.
