We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello Wenlong,


I tried your suggestion but I'm still having the same issue also in Workbench.
Here below all the steps I made:


1) As you suggested, I used the APDL "external model" as input file. Hence I connected it to the Static Structural model.
However, since in Workbench LINK180 is not defined, I had to modify first the APDL code assigning "temporarily" a BEAM188 element instead of link. 


2) Afterward, I modified Engineering data for the thermal bar (defining new Ex, Prxy and Alpx) and I inserted an APDL Command code in Line Body 1 in order to make it recognized as a link (and with SECCONTROL,,1 tension only input).


3) Finally I added fixed contraints and thermal input on the nodes as usual. I also activate non-linear analysis option.


Unfortunately, when I try to update the solution, the following warning/error appear and they seems similar to the APDL ones:



Probably there are some steps I missed or I did something wrong. Please, could you tell me if you found these issues too?


I attach my wbpz file if you want (and if you have some time of course) to compare it with yours.


 


Thank you very much.


 


Regards,
