OpenFOAM to FIELDVIEW conversion
 
I have experieinced some problems with the foamToFieldview9 utility that comes with OpendFOAM 1.5. Has anyone updated this utility?

can you be a little more specific on what problems you are having?

The problems I'm having are when I try to load the FV-UNS file in FIELDVIEW. I working with the settlingFoam tutorial "dahl". The error I get is " The name 'aalpha' belongs to two different functions. One is a Solver Results File Variable and the other is a Solver Results File Varialbe". I get several of these messages when ever I load the results files, clicking okay makes the messages go away, but they are very annoying when working with transient files.

Do you get the same error messages when you try it on another case and what FV version are you using?

I'm using FIELDVIEW 12.2.1. I have just run a simpleFoam example and these file read fine into FIELDVIEW. I suspect the problem is in the settlingFoam tutorial and not the foamToFieldview9 utility.

I suspect that too

I have found the problem. The settlingFoam solver had two variables Alpha and alpha. Whilst OpenFOAM is case sensitive FIELDVIEW doesn't appear to be. The error was caused by FIELDVIEW seeing the two variables as the same.

Hi darrin,

Can you please specify diffrent fractions Alpha and alpha, as to what they clearly indicate,

I had a big doubt in this case,

Thanks in advance,

darrin November 10, 2009 17:07

Hi,
From my understanding, Alpha is the mass fraction of solids and alpha is the volume fraction. The solver is very confusing as both the mass fraction and volume fractions are used throughout. Would be easier to read if both variables had a different name.

Why don't you change the solver to rename Alpha?

darrin November 10, 2009 17:11

That is excatly what I did to fix the problem with the FieldView conversion. I renamed Alpha and re-compilied.

Thanks for your reply darrin,
now how can we come out of this problem, any idea friend,

thanks,

Just make sure when a solver is written all the variables have different names. FIELDVIEW isn't case sensitive so using the same names with different case does not work.
