Dear All,

Should I set idirect =1, even if I don't use aerosol module?

I am working on a domain with  aertyp = 'AER00D0'. I keep all the settings same. I only changed idirect.
When idirect =1 simulation is working correctly.
When I set idirect = 0 ; simulation stops and I have the following error :

SRF variables written at    2008030103    180.0000000000000

Could you please explain me if it is wrong to set idirect=0 for a no aerosol simulation?

Best regards.
