不可以,不能把速度边界的第二相体积分数设置为0到1中间的值,此处只能设置为0或者1。

Fluent User’s Guide->III Solution Mode 35.20.2.3. Checking Boundary and Cell Zone Conditions章节提到:

Assign a value of 0 or 1 for VOF at the inlet or outlet boundary conditions.

When enabling the VOF model, the Volume Fraction in the inlet and outlet boundary conditions for each phase should be set either to 0 or 1No intermediate values are permitted.

因此,对于速度入口边界,不能把相的Volume Fraction设为01之间的值,只能设置0或者1
