求助：请大家帮我看看这个模型中流速怎么设置啊？

loveyuexing

求助：大家帮忙看看我的一个算例是否正确.  急

一个方体内部中间位置处是一个热源，方体下部两根管子，左边为进气管，右边为出气管（二维模型）。
边界条件设置情况如下：
  热源生热率为100000w/m3,边界无滑移设置，进气管处：压力为100p，温度设置298k，设置define/apply
/fluidcfd/velocity/VY=0，出口处：流速设置与进气口相同，出口压力为0。
疑问：在进气口和出气处的速度怎么设置？我参考一本书上是设置VY=0，可是模型中y方向为气体流进方向，为何设置为0呢？？？？？？
以下是我的命令流：请大家帮我看看，指点一下啊，急用
