Doubt on thermal analysis

1-FKI4X8 Dec 15, 2008 1:55 AM

hi everyone I have a problem where in i have to find out the time required to cool down to a specific temperature, i have defined the initial steady state analysis then in the transient analysis i want to find out the node of max temperature to cool down to below 80 deg Celsius. find the attatched document of SXW-2008,which contains all the information of the problem

hi,
did you apply convection somewhere? otherwise your model won't cool down.
for air (free convection) try 10w/m².K

  hi loic i applied convection co-efficient of around 8w/m2.k but i am not able to find out where in cosmos i shoud extract the cooling time down to 80 deg C from 200 deg C.

You can probe a temperature plot and generate a response graph. This will give you a time vs. temperature graph of the selected nodes you probed.
