问:出现“Error:warning : the sue of xis boundary conditions is not appropriate for 2D/3D flow problem. Please consider changing the zone type to symmetry or wall , or the problem to axisymmetric”是什么原因?
答:要进行2D对称模拟时候,需要将求解器设置为axisymmetric 或者axisymmetric Swirl,并且fluent要求将模型的对称轴设置为X轴,网格计算域因为Y轴的正方向。这样设置才能将2D轴对称模拟的对称轴设为AXIS边界,否则就会出现上述提示。
