哪位高手能解释下？谢谢！

在CST仿真时出现下面的错误：  
The calculation seems to be unstable！ Consider reducing the value for the stability factor in the solver specials options or reducing the PBA fill limit in the special mesh properties/advanced. 本文转自微波仿真论坛  
哪位高手能解释下?怎样改正?谢谢！

估计模型有问题，仔细检查一下

Transient Solver [！T]---->[Specials...]---->solver-->Stability factor(設成<1, 0.9,0.85...)
Explanation:
