The air surface is broken，When I use isosurface to generate gas surface
I use %isosurface% -dirin %dirout% -saveiso %dirout2%/Surface -onlymk:2 in examples\mphase_liquidgas\02_ObstacleImpact\wCaseObstacleImpact_LiquidGas_win64_GPU
Why is the gas surface not smooth？Why are there holes？Water does not have this problem，How to solve it？
air Particle files look normal：
Hope to get an answer，thank you！
