floating point error with solar-calculator
 
Hi all,

Im 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 cant 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. Im new in this forum and just worked a few weeks with Fluent.

Hope for your help :)
Thx a lot,

Bodiir
