Hi all,
JM Buchot had earlier posted a model which solves for flow over cylinder using weak form PDE. Weak form expressions of Navier Stokes equations were given as input. But in the expressions he had used, I feel like the signs are reversed for second and third terms in x & y momentum equations (First module in attached .mph file). I get convergence error when the signs are changed.
The actual PDE are as shown in the below link,
Please can someone clarify on this.
With thanks & regards, Alwar Samy R
