Singularity in Stiffness matrix

Please login with a confirmed email address before reporting spam

This is the model of a tritare which has three stretched strings connected at the center. I undestand that it has a multifreedom constraint at the center. But still I believe it should be able to compute the eigenfrequencies for the structure. In the general study it says that the stiffness matrix is singular but I believe it is well constrained.

Any help would be appreciated.
