Hi guys, I am using OPENFOAM-Extend4.1 and I need to import boundarydata. As shown below, the pressure file is included by using #include command. However, when I run the simulation, the error appearred. Do you have any idea?

/*--------------------------------*- C++ -*----------------------------------*\

| \\      /  F ield         | foam-extend: Open Source CFD                    |
|  \\    /   O peration     | Version:     4.1                                |

|    \\/     M anipulation  |                                                 |
\*---------------------------------------------------------------------------*/
FoamFile
{
    version     2.0;
    format      ascii;
    class       scalarAverageField;
    object      values;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

// Average
0

// Data on points
#include "p.data"

--> FOAM FATAL IO ERROR:
incorrect first token, expected <int> or '(', found on line 21 the word '#include'

and the p.data is as following,

400
(
97692.8
97769.8
97847.8
97926.4
98005.3
98084.3
98162.8
.....
)

In fact, the simulation can be run successfully if the pressure file reads below.

Hi,

I have experienced this in the past and I don't know why this error occurs. But the question is: why don't you just use the second format, which actually works? At least, this is what I did in the end.

Best,
Petros

Hi Petros,

Yes, the second format definitely works but I need to arrange a lot of files manually, which takes a long time since I don't know if it is possible to use Matlab for writing a script of allowing writing pressure data append a basic empty file with a header.

Does anyone have ideas?
