Hello Foamers,

Im a beginner. I use OpenFoam 1.5 on Ubunto...
I would like to use the solver buoyantSimpleFoam for a case, so I started the tutorial. But i have this error message when i launch the solver

I think it's probably due to the installation of the librairies, but im not really into it, so i would like to have a confirmation and the solution to solve the problem..
Thanks

maybe you can post the output of foamInstallationTest

if this is working without errors, try running icoFoam tutorial first. I also had problems with buoyantSimpleFoam and then I shifted to OF-1.5.x

Hello Rishi
First, thanks for your answer...
I started by icoFoam, without any problems. I've tried severals tutorials solvers (icoFoam, turbFoam, buoyantFoam) and they worked but not buoyantSimpleFoam. And it is precisely the solver i need for my study

Here you are the results of my installation test. There are 2 No, but i dont know what it means ...

a guess: possibly epsilon is initialised to ZERO in 0 directory. Epsilon has to be non-zero.

try running the buoyantSimpleFoam with turbulence turned OFF and see if it runs.

Epsilon wasnt to ZERO and with the turbulence off, i have the same message...i double checked all my files to see a mistake but i dont find one...
is it possible to send you the case, and you try to run it for me ?... if it works on your computer, i will know that it's from my installation (if you have time of course)
thanks for helping me

Hi Kyian

I saw your case. The problem is that the tutorial has one small error. P is initialised to 0.

Changing "p" file
internalField Uniform 10000;
solves the problem

hope this solves your problem.

regards
Rishi

Hi Foamers,

After the tutorials on buoyantSimpleFoam i've tried to run a simple case, already use in another solver (simpleFoam), but adding temperature in the flow.
This time the solver stops after reading the thermophysical properties. I dont understand how it's possible. I created the case copying the tutorial case of buoyantSimpleFoam.
If you have any suggestions...
Thansk in advance
Kyian

Here is the message i have

One possible problem between different solvers is the use of Pressure units.

Kindly check the pressure units in both solver. It might be a cause of problem. Not sure.
