fluent初始化以后遇到的警告，求大神指导

江南泉

WARNING: Limited wall distance for 1 cells to 1.000000e-12.
         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
         Please select /solve/initialize/repair-wall-distance
         using the text user interface to switch to the
         alternative algorithm.

Warning: More than one cell is equidistant from the specified reference pressure location.
         Reference pressure location will be choosen automatically else specify unique off symmetry reference pressure location
Fluent can try to improve the mesh quality via the TUI command
/mesh/repair-improve/improve-quality

第一个warning我打算后面按提示查看，第二个就看不懂了，不知道什么原因。
