The model has the same number of unknowns and equations: 3308
The model could not be deduced to be symbolically well-posed.
The model has
3280+4*(size(world.x_label.lines, 1)+size(world.y_label.lines, 1)+size( world.z_label.lines, 1))
scalar unknowns and
3242+(if not Connections.isRoot(bodyOfJoint.body.frame_a.R) then 13 else 22)+( if not Connections.isRoot(bodyOfConstraint.body.frame_a.R) then 13 else 22)+( if springOfJoint.lineForce.fixedRotationAtFrame_a then 12 else 3)+(if springOfJoint.lineForce.fixedRotationAtFrame_b then 12 else 3)+(if springOfConstraint.lineForce.fixedRotationAtFrame_a then 12 else 3)+(if springOfConstraint.lineForce.fixedRotationAtFrame_b then 12 else 3)+4*size( world.x_label.lines, 1)+4*size(world.y_label.lines, 1)+4*size(world.z_label.lines, 1)
scalar equations.
However, exploiting the given numerical settings of parameters gives the same number of unknowns and equations:
