Main Help → All Commands → Deprecated Commands → FrictionMM
This command has been deprecated. You should set multimaterial mode friction properties using a ContactMM command instead.
The FrictionMM
command sets the default contact for multimaterial mode MPM calculations to use frictional contact::
FrictionMM (frict)
where (frict)
will result in automatic creation and use of a frictional contact law for multimaterial contact:
(nonnegative number)
: creates a Coulomb Friction contact law with the provided coefficient of friction."stick"
: creates a Coulomb Friction contact law that sticks (or with a negative coefficient of friction)."none"
: creates a Coulomb Friction contact law with a zero coefficient of friction."single"
(or "ignore"
): creates a contact law that ignores contact.
FrictionMM
command sets the frictional properties for all material contact. In simulations with more than two materials, you might want different friction between different pairs of materials. To implement such custom contact, use the Contact
material property (or a deprecated Friction commands within material definitions).
FrictionMM
command is only allowed for MPM analyses.
