The region is read from the output file for temperature. Documentation of ABAQUS explains that the region argument is not available when the temperature is read from file:

A Region object specifying the region to which the predefined field is applied. Region is ignored if the predefined field has an instances member available. Region is also ignored if the predefined field has a distributionType member available, and distributionType=FROM_FILE or FROM_FILE_AND_USER_DEFINED.

Then, how could I do it?

Thanks in advice,

Regards.

Dear Manuel/all,

I am trying to simulate a similar problem. I need to apply temperature from a transient thermal analysis ( temperature in each increment) to perform a thermal-stress analysis (I can not use thermo-stress couple analysis). I have never worked with Python (I did it in Ansys package years ago). Can anyone give me some direction?

thanks for any help

Dear Manuel,

I was unable to identify your problem. If the same model is used both in thermal analysis and static analysis, then there would be no trouble. Are you asking about applying predefined temperature to part of your model? 

Dear Armando,

Perform the operation through ABAQUS GUI and investigate the generated .jnl files for python scripting assistance.

You have to perform the heat transfer analysis first and record the nodal temperatures of the model in the output database file for each timestep. Then use this odb file as the temperature field to your static analysis. Check that total time of the step, time increments and mesh of the model in both analyses are compatible. 

Dear Armando,

As Iman says, what I do is to work from the GUI. Then when you save a progress, a .jnl file is generated in the working directory. From here, you can take all the code you want. Is like if Abaqus were writing code while you are working in the GUI.

In my case, what I need to do is to apply the last temperature from Step2 Job1, as a Boundary Condition for Step1 Job2. I had errors using Boundary Condition, so that's why I'm using Predefined Fields.

If I understood you well, your problem is similar to mine, and I think it can be solved with the four steps I wrote above, but I haven't got a good result yet.

If you don't know anything of Python, I recomend you this book:

http://www.abaquspython.com/

You have some parts of it in that web, if you need more you should look for it in some university library.

Also, I attach one little .pdf that explain tha basics of Python.

Hope this can be usefull to you.

Regards.

Dear Iman,

From what I know I'm just using thermal analysis. I just need to apply one heat flux and study it. The problem is that I want to simulate lot of jobs one after the other, and for that, I need to apply in the second, the result of the first, and so on.

From one Job to another, I have to delete one little part (I simulate one wall being drilled, so I have to delete the material supposedly drilled). I mean, jobs are not exactly the same.

What I exactly need to do is to  apply the last temperature from Step2 Job1, as a Boundary Condition for Step1 Job2. I had errors using Boundary Condition, so that's why I'm using Predefined Fields.

Thanks for your interest,

Regards.

Dear Manuel and Iman,

Thanks very much for your advises. I will read carefully the text attached by Manuel and try to make correct changes in .jnl file. I hope I can return this help.
