Hi,

I am performing a Transient Heat Transfer Analysis.

I need to provide a Time Vs Temperature Curve in the analysis.

My first question is how to insert the data in the inp file, also do we need to refer this curve to a particular

node set or it will be applied to the whole model.

I want to apply this curve to the inner surface of a hollow tube of some thickness.

Right now i have done it in this way:-

*STEP, AMPLITUDE = RAMP, INC = 15000, NAME = TUBE_FIRE

*HEAT TRANSFER, DELTMX = 30.0  

 20      ,1000      ,1.0000E-05,1.0    

*SRADIATE RADIATION,AVG,0.00,0.77

*BOUNDARY, AMPLITUDE = TEMPERATURE

ENTRANCE,11, ,20.0      

EXIT,11, ,40.0      

*OUTPUT, FIELD, FREQUENCY = 10

*NODE OUTPUTNT,

*ELEMENT OUTPUTHFL,

*OUTPUT, HISTORY, FREQUENCY = 1

*END STEP

***************************************************

The curve that i provided is:-

*AMPLITUDE, NAME =TEMPERATURE, DEFINITION=TABULAR

0.0,0.0

60.0,120.0

120,400

180,600
