Hi Patrick / ARTS users, 1) I am trying to run full calculations using the MC_General() method, after setting the PSD fields internally.
2) =>The full calculations do run without errors when I use [psdModifiedGammaMass]. => I see the effects of increase in mass content in the simulation, which means the bulkprop_fields are read into "ws.pnd_agenda_input". =>The only thing is that I don't see is the effect of temperature when after the run. Even when I remove the name "Temperature" from "ws.particle_bulkprop_names" it runs without errors. This makes me wonder if the "pnd_agenda_input_t" is set. => And, when I try extracting the "ws.pnd_agenda_input_t.value" after the successful run. It says that the variable is uninitialized. 3) When I run with [psdModifiedGammaMassXmean],It gives me the following error. Exception: Call to ARTS WSM pnd_fieldCalcFromParticleBulkProps failed with error: Run-time error in agenda: pnd_agenda_array Run-time error in method: psdModifiedGammaMassXmean Negative mean sizefound. This is not allowed. 4) I have attached the sub-function python control file for setting the scattering fields before running MC_General(). Any help would be great.

If yes, then setting the input to pnd_agenda should be automatic. Or are you trying to use the PSD functions separately? Can you clarify this before I try to answer? And maybe also send me your control file.
