Hello

I’m using OpenFOAM 2.4.0 on Ubuntu 15.04 - 64bit version.

When I run some tutorials. for example :
:$FOAM_TUTORIALS/lagrangian/reactingParcelFoam/verticalChannel


I got the below error:

  --> FOAM FATAL IO ERROR: 
cannot find file

file: /home/bijan/OpenFOAM/bijan-2.4.0/run/tutorials/lagrangian/reactingParcelFoam/verticalChannel/0/p at line 0.

    From function regIOobject::readStream()
    in file db/regIOobject/regIOobjectRead.C at line 73.

FOAM exiting
  

Note that I run this tutorial without any changes from their original location in OpenFOAM installation folder.



I know that very users have this problem with tutorial cases and some of them suggested different ways for solving this problem but those ways don't work for my own.

Hi,

Could you describe steps (starting from OS/compiler) to reproduce the error? I have just checked and on my laptop (Darwin Kernel Version 15.0.0/clang-700.1.76) the tutorial runs smoothly at least till

Courant Number mean: 1.805735685 max: 4.899193336
deltaT = 0.0005158730159
Time = 0.0153571

Quick answer @bijan darbari: Don't just run blockMesh and then reactingParcelFoam. You must run:

./Allrun

For more details, read the FAQ "How to run the tutorials in OpenFOAM?": http://openfoamwiki.net/index.php/FA...in_OpenFOAM.3F

And as Alexey pointed out, please provide more details when asking questions here on the forum, as explained here: http://www.cfd-online.com/Forums/ope...-get-help.html

Thanks very much "alexeym" and "wyldckat".
my problem solved by usning ./Allrun command.

and after this topic I will provide more information about my problems when asking questions.

hello friends
i run a simple duct example in openFoam. it's k-epsilon turbulence model.
when i want to show velocity in paraview it stops and exits from it!!
it has this error:


FOAM FATAL IO ERROR:
size 120000 is not equal to the given value of 30000

file: /home/hamide/run/tutorials/incompressible/pisoFoam/ras/1/0.05/p from line 18 to line 120043.

FOAM exiting


how can i six this problem?!!
would you please help?

i guess you did not clean your simulation folder before run again and some previous simulation time step is remained.Therefore, remove all time steps except 0 folder and run again . it should work then
