I've decided to use a sequentially coupled thermal-stress analysis for my model. I was able to successfully replicate the heat transfer analysis part of the model. I'm having a problem when I try to run the stress analysis using the nodal temperatures as a predefined field. Here is what I'm doing:
Using the same model that I used for the heat transfer analysis, I delete the heat transfer step and create a static, general step with the same time increments as the heat transfer model.
I apply the appropriate load and boundary conditions.
For the predefined field, I selected the temperature distribution "from results or output database file". Then I selected the .odb file from the heat transfer analysis. There are other options for Begin Step, Begin increment, End step, End Increment. I left all of these blank because I wasn't sure what to put there.
For the mesh, I keep the same mesh that was used in the heat transfer analysis; however, the element was changed to the one that you used in your report.
I run the analysis using a different job than what was used in the heat transfer analysis and I get an error that says this:
*TEMPERATURE MAY NOT BE USED WITH ELEMENTS THAT POSSESS TEMPERATURE DEGREES OF FREEDOM. USE *BOUNDARY TO PRESCRIBE BOUNDARY CONDITIONS ON TEMPERATURE
I've tried to use temperature boundary conditions and I still get the same error message.
Did you run across anything similar to this when you were developing your model? I really appreciate your help!!
