Hi, I'm running into some trouble rigth now, I have two 3D parts that are symmetric: the have a face contact. I´m trying to mesh them via Multizone Meshing.

Since I'm running a VCCT simulation, I need the nodes/elements on both sides of the contact faces to be the same, that's why I'm using a Arbitrary Match Control, but every time I try to mesh my two pieces:

The meshing algorithm cannot find matching topology. Please verify the topology and the position as well as the orientation of any associated coordinate systems. 

My concearn is with the axis, so far I have two axis wich are have the same position and direction, since the faces are identical and adjacent one another, it should work rigth?

Ok, the problem was that, although they seemed as symetric, they were not correctly placed.

But still, it´s not working, my concerne is with the coordinate systems that we have to set, any help on how to do it? I've seen lots of information for cylindrical match control but non for arbitary, so this would be very helpful.

It still didn't work but I managed to get around it. Insted of using a match control, when I would select the method I would insert it twice, one for each body, since they are the same the have been meshed equaly, that make the node matching natural.

Dear, I am also doing symmetric simulation for spring. Unfortunately, I am also facing such a problem but no one is going to response me
