icem画网格倒入fluent后check时出现问题Mesh check failed.
WARNING:The mesh contains high aspect ratio hexahedral
or polyhedral cells.
The default algorithm used to compute the wall
distance required by the turbulence models might
produce wrong results in these cells.
Please inspect the wall distance by displaying the
contours of the 'Cell Wall Distance' at the
boundaries.If you observe any irregularities we
recommend the use of an alternative algorithm to
correct the wall distance.
Please select /solve/initialize/repair-wall-distance
using the text user interface to switch to the
alternative algorithm.这该怎么解决?求教

说明你网格画的有问题,在ICEM里再检查下,有时候会有负体积,或者面和网格没关联
