Nodes temperature in INP file

[Stancler]

Hi everyone, i'd like to specify node temperature in static/general analysis. Im trying to do this by using predefined field, but it doesn't work. I read in Abaqus user manual that I should use input file options, where inputed file contains node number, temperature value. Could anyone tell me what am I doing wrong? Here is my INP file:
*Heading
** Job name: kostka Model name: Model-1
** Generated by: Abaqus/CAE 6.10-1
*Preprint, echo=NO, model=NO, history=NO, contact=NO

where node-temp.inp is:
1, 10
...
...
...
27, 100

Abaqus accept this input file syntax, but after analysis all node temp value are 0. I read in chapter about input file syntax rules that there should be *KEYWORD followed by data lines.
*TEMPERATURE
1, 10
...
...
...
27, 100

But when i add keyword *TEMPERATURE to my input file analysis doesn't work, there is an error "Error in Job-1, in keyword *TEMPERATURE, file "node-temp.inp", Unknown assembly id1.


Thanks for any help

Hi Stancler,

Have you figured out your problem? I have a similar problem, if you can give me some information, it'll be very helpful.

My suggestion is to apply the individual temperatures on each node in CAE

"Unknown assembly id1."

Part-1.1 is the node id, instead of 1.

In general ABAQUS refers to a node, element or set in an instance by specifying name-of-assemble.name-of-instance.ID-of object

Correction to my previous post:

In the file node-temp.inp, you need to have definitions as follows:

Part-1-1.1, 10 instead of 1, 10
..
..
Part-1-1.27, 100 instead of 27, 100

Why? Because Part-1-1 is the name of the instance of the part (Part-1) that you created. Another option is to have a flat input deck and then, 1 will work just as well.
