問(wèn)：出現(xiàn)“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：要進(jìn)行2D對(duì)稱(chēng)模擬時(shí)候，需要將求解器設(shè)置為axisymmetric 或者axisymmetric Swirl,并且fluent要求將模型的對(duì)稱(chēng)軸設(shè)置為X軸，網(wǎng)格計(jì)算域因?yàn)閅軸的正方向。這樣設(shè)置才能將2D軸對(duì)稱(chēng)模擬的對(duì)稱(chēng)軸設(shè)為AXIS邊界，否則就會(huì)出現(xiàn)上述提示。
