The flow mode is chosen as incompressible, so both two fluids are calculated as incompressible, right?

I thought that inter-block boundary type coefficient(alphamb) might affect, so I changed it...

yes, there is an outlet boundary~

the mesh is as followed:

block1
x:0~1.0, nxcelt=50, y:0~0.1, nycelt=5, z:0~0.5,nzcelt=25 ;

block2
x:0.5~0.8,nxcelt=30, y:0.02~0.08, nycelt=6, z:0.1~0.4,...

question about Nested Grid for two fluids

I started a simple flow example:

rectangular block and make it partly nested
half water (depth=0.3m) and half air
a water flow with constant velocity comes from right boundary, u= 0.1 m/s
...
