Hello Everyone,

I have a list of element(tetra4) id and one face index.

Is there any command that can return nodes of the element face?

    I don't know of a way to do this specific procedure.  How are you getting the face index?

    You could create face elements on the solid element and then select the nodes by the face element.

    When you know element ID, you known also their faces and their nodes ID.

    I got the face index by hm_holedetectiongetholedetails command, this command returns circular tubes element id and face index.

    How to create face element on the specific face of solid element?

    Unfortunately, I am not very familiar with the hole detection commands.  Looks like it will give you the rim node ids.  Doesn't look like it will give you all the nodes in the tube.  That would make it pretty easy with a *markintersection between the tube nodes and element nodes.

    You may be able to get the tube nodes with the axis direction (select nodes in the axis direction from the rim nodes) then using hm_appendmark with the by face option to get the nodes in the tube and then *markintersection between tube nodes and element nodes.

    Hopefully that helps or at least sparks another idea of how to do it.

    You can create face elements with the faces panel but now that I understand more what you are doing I am not sure that would help.
