Collocated or staggered grid? -- CFD Online Discussion Forums

October 21, 2003, 23:02	Collocated or staggered grid?	#1
mspilot Guest Posts: n/a	Hi, dear all: I am a little confused at the pressure option of solution. One of these options is "PRESTO" which means Pressure Staggering Option according to the user's guide. I would like to know how it works but I can't find the details in the books. Does it mean that Fluent uses the staggering grid for presssure caculation? Just like the algorithm developed by Patanka? Or Fluent uses collocated grid and combines the algorithm of staggering grid?
