set_mortar()

Set the mortar contact.

A mort contact is a segment-to-segment, penalty-based contact.

set_tiebreak()

Set the contact allow for failure.

A tieback is a special case of this. After failure, the contact usually becomes a normal one-way, two-way, or single surface version.

set_friction_coefficient(static=0, dynamic=0)

Set the coefficient of friction.

Parameters:

staticfloat, optional

Static coefficient of friction. The default is 0.

dynamicfloat, optional

Dynamic coefficient of friction. The default is 0.

set_active_time(birth_time=0, death_time=1e+20)

Set the birth and death time to active and deactivate the contact.

Parameters:

birth_timeint, optional

Time to activate the contact. The default is 0.

death_timefloat, optional

Time to deactivate the contact. The default is 1e20.

set_initial_penetration()

Ignore initial penetrations.

set_slave_surface(surface)

Set the slave contact interface.

set_master_surface(surface)

Set the master contact interface.

set_penalty_algorithm(formulation=ContactFormulation.STANDARD_PENALTY, segment_based_contact_option=SBOPT.ASSUME_PLANER_SEGMENTS)

Set the contact formulation.

create()

Create a contact.
