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

hi

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

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

dear Max,

can you please elaborate...:(

where to define those parameters? i mean which folders?

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.

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..

check this script runAskervein.py

Have you installed pyFoam?

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

Max when i do the command its says:
EVen after i installed the pyFoam it says same things.

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
would probably contain
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

Hi Bernard Below is my ABL file.. I have configured everyhting step by step and all my $ have been already initialised.. still i get error..:(

Ok I was focused on a script which replaced those parameters automatically.
Thanks for the refresh-session, I need vacation...

What is in "include/initialConditions"? Any zero-values accidentally? Please check with implementation.

no zero value..:(

Where did you define these variable? I assumed they were in this include file?
Uref $Uref;
Href $Href;
n $windDirection;
z $zDirection;
z0 $z0;
zGround $zGround;

these are in ABL conditions

Hi izna,

Have you solved the problem？ I‘m trying to do the same case with you and I also find the error:

PyFoam.ThirdParty.pyratemp.TemplateSyntaxError: line 2, col 1: invalid syntax (, line 1)

If you have made any progress, please tell me.

Best regards

pyfoam, templates, error
 

Hello. Newbie on this pyfoam automation thing.

Anybody knows why pyfoam crashes when trying to invoke template.writeToFile?

template.writeToFile(bmName,{'z0':z0,'us':us})
gets the following error:


Traceback (most recent call last):
File "./run_z0.py", line 113, in <module>

:(

I've been having the same problem for a week now but finally I solved it. simply add the following arg to the call of TemplateFile:

wich makes a line like this:

It seems that newer versions of pyFoam (0.6.5) have different expression delimiters than the old ones.
I know its too late to post this but I do it to help others having this problem since it was hard to find a solution for me.

Thanks ZenCFD for the solution. But how did you locate the error?
