October 16, 2022, 12:41	Changing Mesh resolution of Tutorial Case Channel395	#1
Jing Yun New Member Tianxiong Zhao Join Date: Oct 2022 Posts: 1 Rep Power: 0	Hi, everyone. My question is basically 'Using a finer mesh resulted in a different result'. I tried to change the resolution of mesh in the tutorial case Channel395 (pimpleFoam/LES). To be specific, I doubled the number of cell in y direction (normal to wall). After doing this, the turbulence in result disappear, the whole flow field became laminar. Is this reasonable? And does a finer mesh always mean a more accurate result?
