*MPC
13.22 *MPC: Define multi-point constraints.
This option is used to impose constraintsbetween different degrees of freedom of the model.
Products: ABAQUS/Standard ABAQUS/Explicit
Type: Model data
Level: Part, Part instance, Assembly
References:
•“General multi-point constraints,” Section28.2.2 of the ABAQUS Analysis User ’sManual
•“MPC,” Section 1.1.13 of the ABAQUS User SubroutinesReference Manual
Optional parameters:
INPUT
Set this parameter equal to the name of the alternate input file containing the data lines for this
option. See “Input syntax rules,” Section 1.2.1 of the ABAQUS Analysis User’s Manual, for the
syntax of such file names. If this param eter is omitted, it is assumed that the data follow the keyword
line.
MODE
This parameter applies only to ABAQUS/Standard analys es.
This parameter is used only if the USER parameter is included.
Set MODE=DOF (default) for user subroutine MPC to operate in a degree of freedom mode.
Set MODE=NODE for user subroutine MPC to operate in a nodal m ode.
USER
This parameter applies only to ABAQUS/Standard analys es.
Include this parameter to indicate thatthe constraint is defined in user subroutine MPC.
Data lines to define multi-point constraints:
First line:
1. MPC typefrom “Generalm ulti-pointconstraints,” Section 28.2.2 of the ABAQUS Analysis
User’s Manual, or, if the USER parameter is included, an integer key to be used in user
subroutine MPC to distinguish between different constrainttypes.
2. Node numbers or node sets involved in the constraint.
The first 15 nodes or node sets of an MPC must be entered on the first line. If the MPC contains more
than 15 nodes, enter 0 on the nextline to indicate that it is a continuation line and then continue to enter
