Subject: Intersection of two plates
Author: Guus Janssen
Date: 1999-01-15 07:49:00

I'm modelling a plane wall with stiffener plate perpendicular to the wall.
I use shell 181 for both wall and stiffener.

| | (wall) (T=18 mm Width between stiffeners 300 mm)

|Q|===== (stiffener (20x100 or 150 mm))

A pressure load at the left side of the wall will be applied.

At point Q, the intersection of the two planes I choose to define two lines
of nodes, one at the centreline of the wall, and on at the topside of the
wallelements. The connection between these two are made by means of
Contraint Equations.

First the general FE question:
Do I indeed need to model this intersection in this way or should I have
taken the easy way of generating one line of nodes at the intersection
lines of the mid-planes of the two plates?

Second the ANSYS related question.
To generate the CE's for nodes on the two lines I have mede two macro's.
The first one to connect nodes at the keypoint locations of the lines and a
second one for the inetrior nodes of the lines.
In this proces I now arrive in the end with CE's with non unique DOF
errors.
Therefore: Is it possible to check if a node is already on a CE, either as
MAster or Slave?
(Or is there a better way in ANSYS to couple the nodes on two lines)

Thanks
