abaqus 报错 方程约束中独立自由度过度？

abaqus 报错 A group of connected equations has more than 1000 independent degrees of freedom. Abaqus/Explicit cannot efficiently solve this system. It is suggested that the user consider replacing the connected group of equations by some other constraint type. Possible alternative constraint types might include Kinematic Coupling, Embedded Nodes, *TIE etc. 应该如何解决？
