Always the same results !

Hi,
i'm trying to simulate a spray injection in a chamber, I must analyse the depth of penetration and the cone angle of the spray. I vary differents paranmeters : injection pressure, chamber pressure, hole diameter, temperature, ...
I have different macro for the cone angle calculation and for the depth of penetration calculation.
But I have always the same results. Why ?
Thank you
Best regards

Which Starccm+ version are you using?
Can you explain your problem more. How are you inputing your spary angle?

Hi,
I'm with StarCD 3.26. But I´have found the solution : after the PreProcessing I have to save my work and write the geometry fiel and the problem file because I star the job of a server.
I hope it can be usefull for someone else.
Best regards
Simon

The solution is :
I had to write the problem files and the geometry files because I work of a cluster (server) and not direct of star-cd.
