Dimension Error
Dear Friends
I have calculated wall Heat Flux using wallHeatFlux command in terminal. When I run this for a laminar case, it works properly. But when I run this for Turbulent case: kEpsilon model then I got the following error massage: Different dimensions for dimensions: [ 1 -1 -1 0 0 0 0 ] = [ 0 2 -1 0 0 0 0 ] My question is, if Its a dimesional error then how I got the correct result for laminar case? I am really confused !!!!!!!!!!!!!! |
Seems like the second entry is the first one divided by the density. |

Is there anyone who uses wallHeatFlux command to calculate heat flux at the wall for turbulent case? Thanks ... |
I am using buoyantBossinesqSimpleFoam and run the wallHeatFlux command for kEpsilon model. I got Dimension Error. Its created 3 new file, one is k.old, epsilon.old and mut in the 0 folder. When I use this for laminar case, there is no error.
Can you help me? |

Also you could trick the app if your density is on avg 1, just assign the dimensions you need on the specified dictionaries (variable's files) where this errors occurs! |

Previously, I run this for BuoyantBossinesqSimpleFoam laminar incompressible case and then I have calculated the Nusselt Number. It works fine. Since in RAS properties, I switch off turbulent, I didn't get any error. Now I am solving the same problem for turbulence case with higher Ra values. Another thing, for BuoyantBossinesqSimpleFoam, do I have option to enter the value of rho. In transport properties, I have entered the values for nu, beta, Tref, Pr, Prt. Thanks |

maybe it's an application issue, turning on turbulence should not change the postprocessing app's behaviour since ur not changing the physics of the case... i guess the appl only postprocess results. maybe the nusselt application already accounts for both physics, hence dimensions, whereas wallheatflux seems not! check that Code:

Possible solution...
I'm having the same problem. I can solve it putting the thermophysicalproperties file on constant directory. It isn't used by buoyantBoussinesqPimpleFoam, but wallHeatFlux uses it....
You can try, but don't delete tranportProperties. The my thermophysicalProperties is: Code:
thermoType hRhoThermo<pureMixture<constTransport<specieThermo<hConstThermo<perfectGas>>>>>; |
