Lanczos eigensolver encountered numerical singularity or zero pivot. This may happen if a boundary of the computational interval is very close to an eigenvalue, the problem has an unconnected unconstrained region with zero mass matrix, or a system is overconstrained.

连接没有问题的。加上边界条件就可以算了。下面是我的报错信息! Lanczos eigensolver encountered numerical singularity or zero pivot.
