tie problem

[Sesa]

Hello,

I´m trying to solve the problem that I attached (There are 3 materials). When I plot the 2 displacements it is like the material 2 is not tie with the rest of the geometry but If I plot the mesh it look right and I have used the tie command too. I´m not able to find the problem.
Thanks in advance

The mesh you gave has the top nodes of material 3 at the same coordinates as the top of material 2 and the bottom of material 1  -- is this what you want?

If so you can probably tie using

tie mate 1 2
tid mate 1 3

but it may still give problems?

Hello,

Thanks for your reply!!
what I want is to have the material 2 between 1 and 3. I mean the top nodes of 2 at the same coordinates as the bottom of 1 and the bottom nodes of 2 at the same co0rdinates as the top of material 3.

The command

Code: [Select]

plot,OUTLine can help you see what is tied together and what is not tied together.

To find your problem I had to use interactive mode of solution and in plot mode use the mouse to pick a small part of the untied line and then plot each material mesh separately using PLOT,   MATE 1, MESH, etc.
