computeGWlambda method
Computes G*Wlambda, where W are the body velocities
Implementation
double computeGWlambda() {
final ga = jacobianElementA;
final gb = jacobianElementB;
final bi = this.bi;
final bj = this.bj;
final vi = bi.vlambda;
final vj = bj.vlambda;
final wi = bi.wlambda;
final wj = bj.wlambda;
return ga.multiplyVectors(vi, wi) + gb.multiplyVectors(vj, wj);
}
