How to delete contact elements

I have been using HM since 2011. The last version I used was 2017. I recently upgraded to 2020 and found that several options have changed. One of them is the contact surfaces have moved from groups to set segments.

I would always create a bigger contact surface and delete surface elements that I did not need using the F2-> delete elements command.

Now since the definition has moved to set segments, how do I delete elements from a set segment. I am unable to select them using F2-delete elements.

I have attached an image here. I want to delete all the green contact surface elements that do not over lap with the purple set segment.

in newer versions you don't delete them directly.

rather you remove these elements/faces from your surface/set.

Thank you. It worked.

I have another question, where did the contact manger move to? I was trying to create Pre-Tension using the automatic way by selecting 2 nodes? Where did that option move to?

I'm talking about this: https://2020.help.altair.com/2020/hwdesktop/hm/topics/user_interface/utility_menu_abaqus_pre_tension_section_r.htm?zoom_highlightsub=pretension
