请问这是什么问题啊？麻烦各位大侠指点一下
对称轴的定义报错--- It appears that symmetry zone 19 should actually be an axis(it has faces with zero area projections). Unless you change the zone type from symmetry to axis, you may not be able to continue the solution without encountering floating point errors.改了后仍旧报错---Error: Floating point error: invalid number.

开始就定义为轴边界，而且这个轴必须是x轴平行且y>=0

非常感谢！我开始就定义轴边界了可还是报错，不过我的轴y=0，这有什么不妥吗？
