simpleFoam error while running the simulation

ansab · August 12, 2015, 13:58

Hey guys I am new to OpenFoam,

As for my project , I have to simulate an external flow around an airfoil. I did all the steps and successfully create the mesh using snappyHexMesh. I intend to use K-Epsilon model and setup the files according to it. But when I am running simpleFoam command, I am getting this error.

Build : 2.3.1-bcfaaa7b8660
Exec : simpleFoam
Date : Aug 12 2015
Time : 19:36:36
Host : "ka-pc5l"
PID : 9605
Case : /home/kalabor/tutorials/mesh/snappyHexMesh/goe532-airfoil-testsimulation
nProcs : 1
sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE).
fileModificationChecking : Monitoring run-time modified files using timeStampMaster
allowSystemOperations : Allowing user-supplied system call operations

Reading field p

--> FOAM FATAL IO ERROR:
cannot find file

file: /home/kalabor/tutorials/mesh/snappyHexMesh/goe532-airfoil-testsimulation/0/p at line 0.

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

I am stuck here for 2 weeks now. Please help me. Thanks in advance.

Seriously? Two weeks? The error tells you exactly what is failing, there is no p file in the 0 folder.

Go to the tutorials/incompressible/simpleFoam and look how the test case is configured

@ansab: Quick suggestion: Study chapter 2 of the OpenFOAM User Guide: http://cfd.direct/openfoam/user-guide/tutorials/ - because the reported problem is first explained in subsection "2.1.1.2 Boundary and initial conditions"

Dear ssss, the problem is that I do have p file in 0 folder along with all the necessary files required to run the simulation

Okey then upload the case and I will have a look at it (don't upload the polymesh folder because I imagine that it will weight a lot)

Dear ssss, thanks for the reply but I am now successful in running the simulation. The problem as suggested by Bruno, was in the BOUNDARY FIELDS in P, U, K ,Epsilon and Nut files.
