Hi,
I am new to simulation. I am having problems creating a bolt connector.
QTN 1) In this first printscreen, I need some clarifications on which edge/face should I be selecting for the 2 entries in the red circle. In other words, I would like to know what do the 2 fields mean. In particular, the first entry I currently chose the inner circle of the CSK hole. I am not sure if I should choose the outer hole of the CSK hole instead.
QTN 2) Referring to the printscreen below, I am trying to generate a bolt series and again I am not sure what should I be selecting for the field in red circle.
QTN 3) What is the difference between using bolt connector and a fixture? Am I right to say that bolt connector is a special kind of fixture?
Thanks for any help!

A bolt connector instructs the mesher to attach a beam element in the mesh, implying it can stretch and bend like tetrahedral and shell elements. Fixtures are limits on degrees of freedom of nodes of elements.
I don't know much about the bolt series behavior and pitfalls.
In question 1, the meaning of the fields is to tell simulation the length of the beam element by selecting the faces of the csink and tapping hole. You have selected foundation bolt as opposed to csink. For csink bolt I use the conical surface of the csink in the upper window and the cylindrical surface of the tapping drill hole in the lower window. If the foundation type is what you are after, select the edge of the hole where the bolt head would touch. Under Target I have used a plane idealizing "mother earth", which then means that plane is selected in target window. The plane should be set up as a virtual wall. Connector Virtual wall, contact option "rigid" is a requirement for the foundation bolt, at least in 2010.
