Question about 'Amplitude' command

Question about 'Amplitude' command

Question about 'Amplitude' command

(OP)
Hi everyone,

I have been working on a I-section beam model with beam element. I'm a little bit confused of the way using 'amplitude' command.

I tried the following script and it works:

*AMPLITUDE, NAME=temp1, INPUT=temp1,value=relative,definition=tabular
*step,nlgeom,inc=10800
*static
100,10800,1e-5,100
*temperature,amplitude=temp1
beam,1.

But when I modified the script shown as below, the results seems mess and unreasonable.

*temperature,amplitude=temp1
beam,1.,1.,0.7,0.02,0.02

(also didn't work if using: beam,1.,1.,1.,1.,1.)

The reason why I would like to use 5 points is that because abaqus manual says there are five temperature points can be used in I-section. Does anyone know 1) how to apply the same amplitude for 5 temperature points in I-section?

And also 2) how can I avoid applying amplitude into gradient and just apply it for temperature? ,shown as below

*temperature,amplitude=temp1
beam,1,-3.

Any advice would be appreciated. Thanks in advance. :)
