This program solves 2D transient Navier-Stokes Equations using the SIMPLE algorithm and Fictitious Domain / Immersed Boundary method.

See the following papers for more details:

A new implicit fictitious domain method for the simulation of flow in complex geometries with heat transfer S Haeri, JS Shrimpton, Journal of Computational Physics 237, 21-45.

On the application of immersed boundary, fictitious domain and body-conformal mesh methods to many particle multiphase flows S Haeri, JS Shrimpton, International Journal of Multiphase Flow 40, 38-55.

A correlation for the calculation of the local Nusselt number around circular cylinders in the range 10 ⩽ Re ⩽ 250 and 0.1 ⩽ Pr ⩽ 40 S Haeri, JS Shrimpton, International Journal of Heat and Mass Transfer 59, 219-229.

A Makefile is provided to build the program. The program has been tested on several systems however note that this is only distributed in a hope to be useful for learning fixed mesh approaches in CFD.
