请教有关Fluent的问题

我在使用Solve--->Controls--->Solution命令时，遇到如下错误提示：
Warning: It appears that symmetry zone 3 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.
这是怎么回事？
而且在迭代时，又出现如下错误提示：
iter continuity x-velocity y-velocity          k    epsilon   vf-vapor     time/iter

这又是怎么搞的？

且听风吟

Define-》Boundary Conditions  试试将symmetry设为axis，看行不行

icey

我也碰到同样的问题了　边界条件设为ａｘｉｓ也不行。
哪位高手给指点指点啊
