Temperature

In contrast to traditional analyses using Simulation Composite Analysis, you must specify the temperature of the analysis in absolute temperature units (Kelvin or Rankine) as an initial condition.

This requires you to specify a temperature for all the nodes in the model prior to applying any load.

1. Click Tools > Set > Create.
2. Name the set AllNodes, select the Node radio button, and click Continue.
3. In the window, select all of the nodes that make up the plate and click Done.

A node set has now been created on which we can apply the initial temperature conditions.

To add the initial conditions, we will manually modify the input file.

Note: It is also possible to assign the initial conditions inside Abaqus/CAE.

1. To create a job, switch to the Job module.
2. Double click the Jobs icon in the model tree or select Job > Create from the main toolbar. The Create Job dialog box appears.
3. Name the job ASCA_Tutorial_5 and click Continue. The Edit Job dialog box appears.
4. Accept the default job selections and click OK.
5. From the main toolbar, select Job > Write Input > ASCA_Tutorial_5.
6. Open the newly created ASCA_Tutorial_5.inp file using a text editor.
7. Locate the first *STEP keyword, add the *INITIAL CONDITIONS keyword and associated parameters prior to the *STEP keyword as shown below. Here we are specifying an initial temperature of 297.15 K to the node set created previously. This temperature matches that of the material environment when AS4-PEEK was saved.

   *INITIAL CONDITIONS, TYPE=TEMPERATURE
   ALLNODES, 297.15
   *Step, name=ApplyLoad
   *Static
   0.05, 1., 1e-05, 0.05

8. Save the input file

Note: Depending on the Abaqus version used, the input file my vary slightly.
