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

Is this the hotRoom tutorial? Did you try 1.5.x?

Thanks Mattijs for your answer.
Yes it's the hotRoom tutorial. I succeed to do it with buoyantFoam, but with buoyantSimpleFoam, i have the message i posted, even after i change the mesh configuration.
And no i didnt try the 1.5.x version. Maybe i will when i have time, but i prefer stay in 1.5 first.

Hi all,

I'm having also trouble with buoyantSimpleFoam! I get the error message, too. It vanishs if the initial values for internal field of "p" is set to 10000 (As the boundary conditions). Is this a failure in tutorial setup???
In my understandig p is absolute pressure (for calculation of density?) and pd the relative pressure?!

im not sure it's a problem from the tutorial... I understand the p and pd exactly like you. it looks normal to initialise the pression field with the absolute pression. but it's not so obvious when you are a beginner lol
