When I use openfoam turorials multiRegionHeater when I write blockMesh in terminal there isnt any problem but when I write chtMultiRegionFoam terminal write this :

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, const word&)
in file db/Time/findInstance.C at line 188.

FOAM exiting


what's the problem?is anybody now ? I exactly copy the openfoam tutorial and use chtMultiRegionFoam solver.why it write fatal error?

Hi,

That error means your mesh has not been built correctly.
Running blockMesh is not enough to create a multi region case for chtMultiRegionFoam because mesh has to be split into regions.
Have a look at Allrun script in the tutorial directory and execute it.

tnx for your reply.
do you mean that I should change openfoam tutorial multiRegionHeater to see this solver how work?multiRegionHeater isn't complete?
if multiRegionHeater is incomplete do you have any complete tutorial in order to see chtMultiRegionFoam how work?

No, I said you have to use Allrun script :

I execute ./Allrun and terminal write this:

sajad@sajad-pc:~/Desktop/multiRegionHeater$ ./Allrun
blockMesh already run on /home/sajad/Desktop/multiRegionHeater: remove log file to re-run
Running topoSet on /home/sajad/Desktop/multiRegionHeater
splitMeshRegions already run on /home/sajad/Desktop/multiRegionHeater: remove log file to re-run
Running chtMultiRegionSimpleFoam on /home/sajad/Desktop/multiRegionHeater

creating files for residual

./Allrun: 58: foamLog: Permission denied


why at the end it write Permission denied?

Try first to run ./Allclean.

If you don't have permissions type in the temrinal

chmod +x <name of the document>

tnx for your replying.
I don't use chmod until now.can you tell me how can I use this command for my purpose ? what is +x in this command ? what document I should write to permit me solve the problem ?

[zfaraday]

What you are requesting you can easily find it out by yourself by typing in the terminal:

chmod --help
