Default CFD codes and books: need your opinion

Posts: n/a
Hi all,

I need some usefull info from a CFD guru! I am starting now dealing with the wonderful world of CFD. Up to now I have been using Femlab (version Comsol 3.2) to do some simple simulations (conduction and convection and chemical reaction in laminar flow). Now I have to do the big step to turbolent models and inviscid flow. Is Femlab a good program for CFD simulations?? I am trying to implement Euler equation for an inviscid flow subjected to pressure forces in a 2D domain, but I cannot get in any way convergence. Another question...any hint for a good book for a beginner in CFD (if possible with finite element method approach)?

Thanks in advance for any suggest! Regards

Giovanni Mattarolo

forgett femlab, finite elements,use a good old fortran and finite volumes. Try J.D. Anderson Introduction.......and you will be lucky

Ciao Giovanni,

mi sento espressamente di consigliarti i seguenti libri:

Ferzinger, Peric; Computational Methods for Fluid Dynamics Anderson; Computational Fluid Dynamics - The basics with applications

Patankar; Numerical Heat Transfert and Fluid Flow (anche se un libro po' datato davvero ok! per la il metodo alle differenze/volumi finiti)

Ziekewicz, Taylor The Finite Element Method. Fluid Dynamics

Poi io farei decisamente un giro sul sito del Laboratorio di Calcolo Scientifico del Politecnico di Milano:

i testi prodotti dal prof. Quarteroni, capo del medesimo gruppo, sono poi di altissimo livello.

Modellistica Numerica per Problemi Differenziali Matematica Numerica

i quali per riguardano l'aspetto puramente matematico della soluzione dei problemi differenziali che sono alla base della dinamica dei fluidi e non solo.

Poich ti occupi di Turbolenza per quanto riguarda i modelli d'obbligo la consultazione di:

Wilcox; Turbulence Modelling for CFD Mohammadi, Pironneau; Analysis of k-epsilon turbulence model.

ed in tal proposito molto buono il materiale messo a disposzione dal prof. L.Davidson della Chalmers University di Goteborg (su Google ci si arriva molto facilmente).

Mi dispiace non poterti minimamente aiutare sulla parte impletantativa dei codici in quanto il mio interesse puramente teorico.

If you decide for CFD with FEM: P.M.Gresho, R.L.Sani, Incompressible flow and the finite element method, Vol.2, (1998), John Wiley & Sons This book is amazing and very much referenced.
