BC are deleted or changed every time I open a model, how can I solve this?

Hi, 

I use 2022.2 Altair Hyperworks version and every time I open a model, the BCs I created the last time I edited the file are changed or deleted. Constrains are deleted and forces change the application direction. Thus, I have to define them again. 

Does this happen to someone else? How can I fix this?

 

Thanks

Hello,

No this is not a typical behavior.

What solver are you using? 

Can you share the model or the setup?

You might also want to try exporting a solver deck to verify your setup.

thanks

Hi,

I am using Abaqus solver. 

I am afraid that for security reasons I am not sure I can share the files. But, I just created the BCs from the menu below, shown in the photo. 

As I mentioned, once I close the file, when I open it again, some BCs are deleted or changed. 

First picture, what I originaly created, second, what appears when I open the file again. 

Thanks!

Since you can't share your model, I would make sure you are looking at the input decks. That is true way to verify. Visually what I see is the difference between legacy loads and the new migrated loads. No loads should be changed or deleted.
