4. Common object for one-sided contact

4.1. Item NDIMCO

This object is common to all formulations of unilateral contact, so it does not exist in the case of the formulation LIAISON_UNIL.

Notes:

• The number of points only makes sense in the formulation CONTINUE (it then depends on the integration diagram). For discrete methods, it is equal to the number of slave nodes;

• The term « actually in contact » corresponds to the case where the quantities are linked to a calculation resolution (RESOLUTION =” OUI “in DEFI_CONTACT). For example, for the nodes:

• NTNOE: total number of slave nodes;

• NTNOEC: number of slave nodes on which we will do the calculation;

• NTNOEV = NTNOE - NTNOEC: number of slave nodes on which we will only do the pairing;
