建模简单修改出现Error： 1100

预先用COMSO图形界面生成两个圆命令如下：

g1=ellip2(0.03,0.03,'base','center','pos',[0,0]);
g2=ellip2(0.01,0.01,'base','center','pos',[0.01,0.01]); %圆心在[0.01,0.01]

将其保存为.m文件，在comsol和matlab下运行都没问题，但是仅仅将第二圆的中心改成[0，0.01]，即g2=ellip2(0.01,0.01,'base','center','pos',[0,0.01]);

comsol报错Error： 1100，some errors were found in the FEM structure。

Matlab报错：
fem.appl{1}.bnd.type{2} must have any of the values 'ss', 'V', 'V0', 'sh', 'fp', 'term', 'port'
??? Error using ==> fem2jxfem at 45
Errors found in FEM structure.

怎么回事呢？
