<\/p>\nHello everyone! I am doing a coupled transient electro-thermal simulation in the coupled field module in workbench r2023r1. I have automated the entire simulation with python scripting and during restart I use apdl commands to change the rezistivity of certain elements at a certain step then solve again. Unfortunately i encounter an error that only appears as a warning in the interface as seen in the image and it is not detailed in the err file or anywhere else. <\/p>\n
<\/p>\n
Here is the code i am using to do the restart. command 2 is created before the restart to avoid creating it again and again.
Has anyone encontered this problem? I read some posts about the rst file that has to be disposed of before another solve or that it may be a bug. Any suggestions would be great. Thank you<\/p>\n
