LATENT HEAT IN ABAQUS

LATENT HEAT IN ABAQUS

LATENT HEAT IN ABAQUS

(OP)
Hello guys,
does any one have an idea how Abaqus deals with latent heat and how adds its effect to the heat transfer equation, I searched their manuals and it sounds that there is nothing mentioned about it. I am trying to include the effect of latent heat by two ways:
1-convert the latent heat into specific heat by dividing on the time range when I have change in phase, and then add this extra specific heat to the specific heat amount that I already have.
2-model the latent heat explicitly by option provided in Abaqus.
the problem that I don't get the exact same results by using both ways, the curve behavior is the same, but there is some divergence in the temperature range when phase change is occur. It sounds reasonable to me that I should get almost the same results.So, any idea why this difference occur?

thanks in advance
