I'm leaving if I didn't get any answer
 

Dear Sir/ Madam,
Solar still, water and water vapor.
Photo is attached
1- Water evaporate due to solar radiation
2- Water vapor condense due to the temperature difference
3- collect the condensation
I need to know the condensation rate (mass flow rate)
Please help me please
Regards
Some precise questions;
1- Is VOF a successful tool?
2- Number of phases 2 or 3 ?
3- Explicit or implicit ?
4- Transient or steady ?
5- Sharp or dispersed interface ?
6- Solar model ?
7- viscous model?
8- enable surface tension?
9- SS of enthalpy for each phase?
10- solution method?
11- URF values?
12- standard or hybrid intialization? Attachment 55234
