floating point error with solar-calculator

Bodiir · November 2, 2011, 09:28

Hi all,

I´m trying to use the solar-calculator in fluent. The model is a simle block (one volume, six faces, 8m x 10m x 15m).

Sadly i got some errors and problems and i can´t find my mistake...

First of all i got the message:

Error: class CxFrameNT does not recognize attribute right-of.
Error: class CxFrameNT does not recognize attribute below.

when i read my casefile.

The second problem is, that i cant change the values under define->models->radiation [illumination parameters]. It would be best to calculate these parameters (Direct Solar Irradiation and Diffuse Solar Irradiation) with the solar calculator but it doesnt work. Also if i type a constant value and click ok the settings werent saved.

After all i got a "floating point error" each time i enable "use total irradiation from solar load model settings" under "boundary conditions"->semitransparent wall->"radiation".

I will add a summary with my settings. If you need more information please tell me. I´m new in this forum and just worked a few weeks with Fluent.

Hope for your help

Thx a lot,

Bodiir
