但是,在输出网格文件时候,失败,出现以下提示:
WARN: Boundary Entity outflow does not contain any valid entity and is not written.
WARN: Boundary Entity wall does not contain any valid entity and is not written.
ERROR: Continuum or Boundary condition specified on entity face.1 is invalid for fluent 6.
请问:二维模拟不允许faces作为边界条件吗?只有三维模拟才可以允许faces做边界条件吗?
