today i tried to simulate some mechanical part's transient analysis, while doing that thing i realised that something was going wrong. to describe the problem i've prepared a summarized model.
transient total time:60sec (increment:1sec) 60 steps
initial temp(solid model): 50 celcius
convection coeff:25 W/m^2.K
ambient temp:20 celcius
i applied analysis for both aluminium(6061) and steel(st37-2) materials.
when i look at the cooling curves for the same point; i realised that there is almost no differences between to simulations.
Owing to having the same volumes; aluminium has to cool faster than steel, doesn't it? its
there is something wrong but i couldn't find the reason yet.
cooling curve for St37-2
cooling curve for6061 Alloy
model is also attached.
