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

You can use buoyantPimpleFoam with gravity turned off and laminar model selected in the turbulence properties.

Check the tutorial case in
Code:
 $FOAM_TUTORIAL//tutorials/heatTransfer/buoyantPimpleFoam

HI,
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.

can i use it for steady laminar flow, incompressible, without bouyanct force.
by using g= 0 m/s^2, model=laminar and deltatime = 1

floquation will become famous soon enough
Don't ask the same question twice.
