Dear all,

I am simulating the transient flow past a cylinder using C-grid mesh with, Laminar,

using different pressure velocity coupling I am only able to get 0.39 as the amplitude of the C-l and C-d is also slightly high, I have used Simple Scheme, with second order of momentum and pressure and Bound Second Order for Time with these settings I am getting C-l as 0.399 for 117K mesh count and 0.389 for 315K mesh count,



With Piso and only neighbor correction C-l 0.391 for 117K and 0.401 for 315K mesh count,

With coupled solver, and flow courant number 2e^7, the results are more or less the same.

Please help me I am working for more than 1 month but only able to get these results with this much accuracy ideally the amplitude of c-l should be 0.3321 and time avg value c-d must be 1.33.

I have referred to one answer on the forum that guy solved the problem related to the overpredicted value, but did not reply back on the forum

Please help me out

Thanks in advance.
