*CONSTRAINED_SHELL_IN_SOLID
Hi,
I have a problem while solving a concrete beam. Normally concrete is rectangle or square in shape and steel rods are placed inside it. Now i want to give a contact for this. What type of contact is preferred?
In LS Prepost they have a constrain called *CONSTRAINED_SHELL_IN_SOLID with this we can assign it. But in hyper mesh is there any contact like this. Please help me its urgent.

Hi Sourav Das,
Thank you so much for your reply.
I understand it. But i want to conform once again. I attach you the photo of the model which i going to mesh and analyze.
Outside is concrete box and inside Steel bars are there. Can we apply Freeze property here?
Because in LS Prepost there is a separate commend for this type of problem. So i want to know it.
And at final i want to run it in LS-Dyna so the card generate by this will not be the problem there?
Altair EmployeeHi PabhuMan,
If you are using the Optistruct as solver then you can use Freeze contact to achieve the same.
Hi PrabhuMan,
You can use freeze contact, The FREEZE condition applies to all respective contact elements, no matter whether open or closed.
This means basically, that the two contact surfaces are 'glued' and will transfer all loads / motions between master and slave (also known as Tied Contact).
SLIDE – Sliding contact.
STICK – Contact with stick condition (stick applies to closed contacts only).
FREEZE – Enforced zero relative displacements on the contact interface (applies to both closed and open contacts).
