Dear all

I am doing a flat roof pressure simulation using LES. I want to observe the pressure in the front of the building.I found a method to use probes. So I add the following codes in controlDict:

functions
{#includeFunc probes}

And I also made a copy of /opt/openfoam4/etc/caseDicts/postProcessing/probes/probes to the systerm folder of my case. The codes in probes are the following:

probes:

FoamFile
{
version 2.0;
format ascii;
class dictionary;
object probes;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

probes
{

#includeEtc "caseDicts/postProcessing/probes/probes.cfg"

writeControl adjustableRunTime;

writeInterval 0.005;

fields ( p );
probeLocations
(
(7.7 0.4 3)
);



}

When I using simple at the terminal, the error happens:
--> FOAM FATAL ERROR:
Unknown functionEntry 'includeFunc' in "/home/olmati/OpenFOAM/olmati-3.0.1/run/Wangjingxue/Flatroof5/system/controlDict" near line 56

Valid functionEntries are :

7
(
inputMode
codeStream
include
calc
remove
includeIfPresent
includeEtc
)


From function functionEntry::execute(const word& functionName, dictionary& parentDict, Istream&)
in file db/dictionary/functionEntries/functionEntry/functionEntry.C at line 83.

FOAM exiting

Could somebody have some idea for this? Many thanks!

Hi,

In OpenFOAM 3.0.1 there is no includeFuncEntry (see https://github.com/OpenFOAM/OpenFOAM...unctionEntries). It appeared in version 4 (see https://github.com/OpenFOAM/OpenFOAM...unctionEntries).

So, guess, "some idea" would be "use OpenFOAM 4.x".

Hi,alexeym

Many thanks! My openfoam version is 3.0.
I am considering what method should I take to process probe even in Openfoam3.1.Do you have some idea？
I tried the #includeEtc, but the following error existed:

Create time
--> FOAM FATAL IO ERROR:
wrong token type - expected string, found on line 56 the word 'probes'

Hi,

You can try other entries as well or you can just use search on the 3.0.x repository [1] to find out, how you can add probes function object to constrolDict in OpenFOAM 3.0.x.

hi,alexeym

I will try this.Many thanks for your help!

Hello guys
I'm new to the forum.
I have this problem ... I have to run a two square tandem simulation and would like to evaluate downstream pressure fluctuations of the two cylinders through probes and probesDict.
When I start the simulation, however, the log file pulls me out of this error:

--> FOAM Warning :
From function virtual void Foam:robes::findElements(const Foam::fvMesh&)
in file probes/probes.C at line 119
Did not find location (0.15 0 0) in any cell. Skipping location.
--> FOAM Warning :
From function virtual void Foam:robes::findElements(const Foam::fvMesh&)
in file probes/probes.C at line 119
Did not find location (0.06 0 0) in any cell. Skipping location.
--> FOAM Warning :
From function virtual void Foam:robes::findElements(const Foam::fvMesh&)
in file probes/probes.C at line 119
Did not find location (1 0 0) in any cell. Skipping location.

ControlDict looks like this:
...
functions
{
#include "forceCoeffs"
#include "forceCoeffs2"
#includeFunc probes
}
CheckMesh says geometry it's OK.
Thanks again for the help you give me.

Hi,

In simple case there are two possibilities:

1. You made mistake with probe coordinates. Could you post checkMesh output?

2. Due to mesh cells distribution, these three probes happened to be in between cells. So you just need to move them a little bit, i.e. try 0.149 instead of 0.15.

Hi alexeym, thanks for the reply.

2) I also tried the second option but it continues to give the same type of error.

Your mesh z is in range [0.05, 0.1], so it is not surprising, that probes with z=0 are outside of the domain and are skipped.

Thanks a lot!!!!!
Now is run
