COMSOL with MATLAB

运行COMSOL with MATLAB，在COMSOL中运行Model Labrary-MEMS Model-Microfluidics Models 中的lamella mixer，然后转到MATLAB，在MATLAB中运行提取矩阵的命令[A,B,C,D]=femstate(fem)，结果出现如下提示：
>> [A,B,C,D]=femstate(fem)
??? Java exception occurred:
Exception:

我随后试验了Model Labrary-MEMS Model-Microfluidics Models 中的所有模型，发现都提示这样的问题，请高手指点如何处理，谢谢。

请仔细阅读femstate的说明文档。这个脚本和femsim都是与Simulink相关的。
