I've recently been attempting to insert my code into an existing EXEDIT subroutine in Autodyn, aiming to achieve temperature transfer functionality within a 2D multi-material Eulerian domain. However, upon execution, it seems that my code isn't producing any noticeable effects. Below is the portion of code I've inserted into the existing EXEDIT subroutine:

I would like to know if this functionality can be implemented through a user subroutine, whether it should be written in an EXEDIT subroutine, and how to modify model parameters during the calculation process and return them to the main program to continue the calculation.

• Version: ANSYS 15.0; VS 2010; Fortran 2011
• Operating System: Windows 10 Professional

Thank you to everyone who can provide assistance. I truly appreciate your support and guidance!

Temperature in the Autodyn multi-material Euler solver is not an element variable. It is a material variable. See the Note D for TEMP in the Section 6.1. Autodyn-2D – Structured (IJK) Solvers from Autodyn User Subroutine Guide.

 

 

Below is the Note D from the Autodyn User Subroutine Guide:

 

To access the multi-material variables, you need to call GETMLT to retrieve the material variables and then call PUTMLT to store them back and clear the memory. More information can be found from the Section 3.6. Accessing Multiple Material Data – All IJK Solvers from Autodyn User Subroutine Guide.
