Use Temperature as Load

Hello,

Can anyone help to understand how do I apply Temperature as Load instead of Heat Flux as in tutorial 'OS-1090_ Linear Transient Heat Transfer Analysis of an Extended Surface Heat Transfer Fin'.

On the Surface where heat flux is applied i need to apply temperature say (150°C).

I created as u suggested on the nodes of 1 face. But I am getting error.

Actually I am applying the temperature load in cycle and hence I am using TLOAD1 card in an load collector in which a table is used to excite the load.

The error message states 'EXCITEID on TLOAD1,7 card references nonexistent DAREA,11.'

Now, Card edit this load collector with Config as const and type as SPC > Edit > in the filed D enter the temperature value.

Hello,

I try to run thermal analysis using temperature load. I have only one component. I want to apply different temperatures on different surfaces. But I am getting error. Is it possible to specify more than one TEMP or TEMPD load?

Hi Nihan,

TEMPD card can be used to assign a temperature for those grid/s that have not been given a temperature on a TEMP entry.

So for the same component you can pick few nodes and assign the temperature using TEMP card and for the remaining nodes assign a different temperature value using TEMPD card.

Thanks
