March 15, 2020, 16:31	Meshing in Fluent	#1
rizwan4081 New Member Muhammad Rizwan Join Date: Mar 2020 Posts: 11 Rep Power: 6	Greetings. I am new to Ansys Fluent. I am doing an analysis where I am analyzing the flow over a car in a tunnel. I have the Student version of the software with a limitation on the number of mesh elements of a max being 512000 cells. I would like to know how to calculate the minimum element size of the mesh? The tunnel is 500 meters and by default the mesh element size is 25 meters, But I want to know if there is a way to calculate a minimum size so as to guarantee the convergence of solution?
