Detailed Description

Places linear springs between all degrees of freedom of 2 nodes.

To form a tie specify the 2 nodes that will be linked as well as the spring constants for translational and rotational degrees of freedom. All translational degrees of freedom will be assigned the same spring constant. The same is true for rotational degrees of freedom, although the spring constant does not have to be the same as that used for the translational DOFs.

// create the tie between node2 and node3
unsigned int nn1 = 1; // i.e. the second node in the node list
unsigned int nn2 = 2; // i.e. the third node in the node list

// define the spring constant for x, y, and z translational DOFs
double lmult = 100.0;

// define the spring constant for x, y, and z rotational DOFs
double rmult = 100.0;

// form the tie
fea::Tie tie1(nn1, nn2, lmult, rmult);
