大家好。我在做一个气泡在液体中移动的问题。建立的是三维模型,液体为胶层,中心靠上部位有一个扁平气泡(由一个部分球面加上一个平面组成),两部分分别建立两个solid模型。气泡上表面(平面)与胶层上表面(平面)处于同一平面上,该面上还承受一薄板,为流固耦合界面。现在的问题是:胶层与气泡的接触面为一小部分球面,应设置流流界面(FFI),设置好后计算,软件提示如下错误:
*** ERROR *** CODE ADF2728:
Boundary condition (label) 2 has been applied to an improper location
The left side of the location is Out side of the domain
The right side of the location is Fluid element group

are physically meaningful.
