Use Weak Contribution in Solid Mechanic Module

Please login with a confirmed email address before reporting spam

I would like to use Weak Contribution in Solid Mechanic Module on All Domain of a model. But when use Solid Mechanic Module, Linear Elastic Material is added automatically as default.

Linear Elastic Material also has equations, but I would like to use my weak equation instead of COMSOL equation.

Can I use Weak Contribution in Solid Mechanic Module without effect from Linear elastic material?
or
Can I input my own weak equation in Solid Mechanic Module?

Thank you

In case someone is still interested:

"In the Model Builder, when you right-click any physics interface node and open the
context menu, there are additional feature nodes that can be added to your model. To
enable this feature and add the following nodes, click the Show button ( ) and select
Advanced Physics Options"

Weak contribution and some other options become available (visible) then.
