I am using VOF model,for modeling boiling in a horizontal tube,the flow is laminar,and the wall tempreture is 403 kelvin,water is saturated373 kelvin,but it doesnt work properly & doesnt show phase change,& volume fraction of phase 2nd is zero during the process.
I added a source term but it doesnt have good result,what can I do?


tanx alot

You should use UDF to definite the source term!
