simpleFoam crash fast!

Hi..

after meshing my case successfully, I run simpleFoam, to obtain the following error.

can anyone tell me what should i do?

Looks like you forgot the word "uniform" for your velocity inlet boundary condition

izna	August 12, 2013 00:46

hi

this is my file for U.. I have not forgotten the word uniform..:(

Quote:

#include "include/initialConditions"

dimensions [0 1 -1 0 0 0 0];

internalField uniform $flowVelocity;

boundaryField
{
#include "include/ABLConditions"

outlet
{
type zeroGradient;
}

inlet
{
type atmBoundaryLayerInletVelocity;
Uref $Uref;
Href $Href;
n $windDirection;
z $zDirection;
z0 $z0;
value $internalField;
zGround $zGround;
kappa 0.4;
}

terrain_patch0
{
type uniformFixedValue;
value uniform (0 0 0);
}

ground
{
type fixedValue;
value uniform (0 0 0);
}

all your "$"-parameters are not set.
I assume you should run a script which replaces all the $-parameters with right value

izna	August 12, 2013 03:02

dear Max,

can you please elaborate...:(

where to define those parameters? i mean which folders?

-mAx-

August 12, 2013 03:18

I am not experienced with atmBoundaryLayerInletVelocity, but for sure the third line of your U file should look like "internalField uniform (0 0 0);"
where (0 0 0) is the velocity vector for domain initialization.
But you have "internalField uniform $flowVelocity;"
$flowVelocity is a parameter for a script, which should automatically set the velocity vector (understand replace $flowVelocity with the right vector).
So either you get this script, and you run it, or you replace all the "$-parameters" with their right values.
The script is not a part of OF.

izna	August 13, 2013 03:52

hi thanks for the reply dear max

can you tell me what does the followingh error means? I get this when i run ./Allrun

edit "Allrun" file and check what it is supposed to do.

it is supposed to do the above..

i got that case from the net and each i am geting the same error..

Have you installed pyFoam?

izna	August 13, 2013 05:00

On installing the pyFOam and again running ./Allrun.. i obtain the foll error..

Max when i do the command its says:

runAskervein.py: command not found

EVen after i installed the pyFoam it says same things.

August 13, 2013 06:59

with check I meant edit the file and check what it is executing...
For running it, you have to know which arguments etc... you have to enter.
But I don't know exactly what does this script and I suggest you to ignore it and go back to basics: set your BC properly and run simpleFoam.

simpleFoam error due to atmBoundaryLayerInletVelocity

Each time same error.. I need help badly

This is not correct as

Code:

#include "include/initialConditions"

would probably contain

Code:

flowVelocity (10 0 0);

this should work fine.

But all the $-parameters should remain in the U-file, or they will be replaced with their rihgt values?
I never used "include/initialConditions

The correct values will be used. Pretty handy if you need variables at multiple places. You can include any file that you wish. For example, sometimes I include the blockMeshDict in the setFieldsDict, works perfectly fine.

Especially in OF 2.2, there are some advanced possibilities, see: http://www.openfoam.org/version2.2.0/pre-processing.php
