I tried to use Command(APDL) Scripting in Workbench which includes iterative heat load using *do loop. I want to extract the temperature in /POST1 during each iteration and use it to update input under /SOLU. However, a single *do loop cannot take /SOLU and /POST1 together in workbench. But this flexiblity is there in APDL(classic). I cannot put /SOLU and /POST separately, as I want to update input load based on postprocessing data. Is there is any way to solve this kind of problem. I am using 2022 R2 enterprise version.

APDL screenshot is attached:

Hi

Perhaps this helps

To have a temp. dependent heat generation use this:

The link is not much helpful. There has to be some method for Command(APDL) in workbench to combine /SOLU and /POST1 in single *Do loop.

Hi

You said: 'I tried to use Command(APDL) Scripting in Workbench which includes iterative heat load using *do loop. I want to extract the temperature in /POST1 during each iteration and use it to update input under /SOLU.'

 

So what do you want to get from POST1 - is it temperature?

And what do you want to update (BFE,,HGEN?) using the post1 results above in your input?

 

Yes there are some ways, but the way you do it is wrong as you can see from the error message (BFE is a /PREP7 or /SOLU not /POST1 command), and it is outside what we (Ansys employees) can help with here as it requires extensive apdl scripting - perhaps some other users can help, but if you answer in detail my questions, there might be an easier way of doing what you want.

Thank you

Erik

Actually I am updating HGEN with each iteration under /SOLU, this will provide some Tmax in /POST1. I wanted to get different Tmax based on each HGEN applied. It is true that /SOLU is not updating based on any data from /POST1. But why cannot I iterate and get Tmax for each HGEN. The other way can be manually give HGEN and record Tmax. But I wanted to automate the process. The same thing can be easily done in APDL(classic), so why can’t we do it with Command(APDL) in Workbench.

I just want to know, where I am committing mistakes. Is there any way to this analysis using Command(APDL) in Workbench?
