Transient temperature analysis

svez

Hi!

I would like to make a transient analysis with temperature. I mean:

Going for example from 17 to 23 degrees of the temperature of a body in 1 hour. Making steps of 10 minutes for example (total of 6 steps).

I tried to do it with TABLED, TSTEP and creating a temperature LOAD but it doesn't work. It says :

' *** ERROR # 2094 ***
EXCITEID on TLOAD1 # 17 data references follower force or nonexistent
DAREA/static loading with ID # 16.'

Could you help me?

Big thanks in advance

Thank you

Thanks! Now I changed the load step to a transient analysis because I am gonna set up an ambient temperature and with convection and conduction see how the temperature increases in the solid and also how it deforms.

Nevertheless in a tutorial about 'Transient Thermal Stress Analysis' it says that I have to create a CONVECTION interface and refer it to the Material I just created.

That material is also created in the tutorial and it is a MAT1 with data for MAT 4

But when in the convection card image I try to select that material it doesn't appear

How could I fix it?

Thanks!
