Default speckled appearance in radiation
Posts: n/a
Dear all, does anyone knows why the results for temperature look speckled after a radiation (montecarlo) simulation for a windowed room?. Ive tried with different coarsening rates from 64 to 4 thinking it was the reason but the speckling remains. The length scale of the speckles is about 6 elements. The number of computed rays is 1e6.

any suggestion will be wellcome. Thanks

Dear Pi,

Your best bet here is to contact your support representative, and pass them your results file. Are you using 5.6 or 5.7? Multiband or Gray?

Good luck, Juan Carlos

Hi Juan Carlos, Im still using 5.6 and two bands (0-2.5 and 2.5-1000 microns, solar and thermal bands). Its suppossed Ill see to my representative next week with more questions. I just thought that this problem was easy to solve and due to some mistake in the settings. Do you know if the MC radiation model is well tested in the 5.6 version?I cant get either directionality in the results when I set a directional source of radiation.

Thanks a lot for your kind answers
