I have noticed the new Phase-Field Damage multiphysics interface in 6.2, i want to do some simulation about heat shock induced crack propagation with this interface, i wonder is there any tutorial model that we can refer to.

thank you.

Dear pengcheng dou,

Currently, we do not have an example available that shows how you can combine phase field damage with thermal effects. We are planning on providing an example model on this topic, however.

For now, you may refer to this tutorial on phase field modeling of damage in solids: Brittle Fracture of a Holed Plate. It uses the Damage subnode instead of the Phase Field Damage multiphysics coupling, but many settings are similar.

Best regards, Adam Wahlsten, COMSOL

Dear pengcheng,

Please have a look at this model for a multiphysics example with both solid and thermal damage.
