Material Change
Ex: Rock to Concrete
Node 1

• One material different fields
– Confusion on material definition

• Same nodes different elements
– No stress on new material
– CAE can’t do that
Element 1+
• Restart
Element 2001
– Too much restart for big models

Abaqus
• MODEL CHANGE
– Activate and Deactivate mesh
– CAE is ok!
– Plugin make it easier
