Error in chtMultiRegionFoam
hi,
i am trying to use chtMultiRegionFoam solver to treat heat transfer in walls.But i couldnot get the results as there is error msg in terminal. The error msg is like this, kiran@kiran-desktop:~$ cd $FOAM_RUN/tutorials/heatTransfer/chtMultiRegionFoam/multiRegionHeater kiran@kiran-desktop:~/OpenFOAM/kiran-1.7.0/run/tutorials/heatTransfer/chtMultiRegionFoam/multiRegionHeater$ chtMultiRegionFoam /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 1.7.0 | | \\ / A nd | Web: www.OpenFOAM.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : 1.7.0-279cc8e8233b Exec : chtMultiRegionFoam Date : Aug 02 2010 Time : 17:11:51 Host : kiran-desktop PID : 2067 Case : /home/kiran/OpenFOAM/kiran-1.7.0/run/tutorials/heatTransfer/chtMultiRegionFoam/multiRegionHeater nProcs : 1 SigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create fluid mesh for region bottomAir for time = 0 --> FOAM FATAL ERROR: Cannot find file "points" in directory "bottomAir/polyMesh" in times 0 down to constant From function Time::findInstance(const fileName&, const word&, const IOobject::readOption) in file db/Time/findInstance.C at line 175.

Hi! Tracing back the error is quite simple...

If you have no idea of what you are doing, use the ./Allrun script and copy paste every line to your terminal, so you can understand what does what. Also, cross check the following thread: http://www.cfd-online.com/Forums/ope...rial-15-a.html. Even if it is written for OF 1.5, most of it is valid for OF 1.7 as well. Lastly, please note that there is a bug on chtMultiRegionFoam in OF 1.7 that has been fixed in 1.7.x (see here). enjoy mad |
You can't just run chtMultiRegionFoam. You have to run the Allrun file. The Allrun file contains necessary utilities for the solver to work.
The output of the solver is heated air slowly moving above two warm plates. |
Hello Maddalena, do you mean that we have to create a polyMesh file? or it'll work only by using the Allrun file???
Thank you Daniel |

OK, It's done. Many Thanks.

Are you sure that you have run `blockMesh` properly?
