How to swap master-slave surface by TCL?

Altair Forum User

My question is how to use TCL scripts to swap master-slave surface. Like the figure attached, I want to swap master-slave surface of those highlighted contact pairs.

I want to use Young's modulus to decide which surface should be master, and the other to be slave. Master surface should have higher Young's modulus.

So, how can I write this if statement and swap the master-slave surface?

My model is also uploaded, and I have created the contact pairs. But the contact pairs have'nt been swapped.

Can anyone help me please?

Can you find any menu command to do it?

If there is not, it will consume much time to parse and hook into altair code, since it is no designed to swap master-slaver

Try exporting data, and show us text lines about interface definition, we may look for a workaround.

Hi, thanks for replying.

I think the function is in the CW.tcl file, and the function is : proc ::AbaqusCW::swapMasterSlave { args }

The problem is that I have no idea how to use it.

The function requests an interface item must be selected on data tree.

Let's looking in tk tree selection command later
