Is there a time-based (not damage-based) deletion/deactivation of elements in every time increment during a step? How can we define it, is there a subroutine for this?

Hi,

You can use UMAT and VUMAT subroutines to solve your problem. If you need more information and how to use the UMAT subroutine for your current problem, refer to this link: https://caeassistant.com/product/umat-subroutine-vumat-subroutine/#1576700058538-e629a8e0-afbdf314-3e84

Also, you can use the USDFLD subroutine because you have access to the element number there. I think it would be easier to use this subroutine because you don’t need to define material properties. Just put some conditions time-based, damage-based, etc. and delete any elements you want according to the conditions you have defined. Note that mesh deletion in the USDFLD subroutine is available only from the Abaqus 2017 version onwards. Refer to this link for the USDFLD subroutine: https://caeassistant.com/product/usdfld/

I hope I could have helped you.

Best luck.
