"Does OpenFoam have a GUI for creating my model's"

Yes, FoamX can be used to set up dictionaries, initial fields, etc.

"and meshing it"

No, you have to use 3rd party meshers and convert them to OpenFOAM format.

"for postprocessing"

Yes, its called paraFoam (paraview).

thank u.And OpenFOam will support for Lam/Mpi Cluster But i want to do it in single system..Then why it asking for nsd daemon should be running..

[leosding]

You should have more than 2 CPU in your single system to do lam.
step by step as the manual, first boot the lam with command "labroot", then "mpirun" your applications.
Maybe you should read through the manual before you do something.

Take a look at Ennova CFD (www.ennova-cfd.com). It has CAD import, CAD cleanup, mesh generation, a GUI to set up OpenFOAM boundary conditions and other dictionary files, plus post-processing based on VTK (the same technology as Paraview). The mesh generation types include topology based as well as octtree based (like Snappyhex). Boundary layer generation. Polyhedral meshes as well as tet + prism. Full diagnostics on the mesh are available including quality, skewness, orthogonality and others. Ploting of bad elements and cut planes of the mesh are available.
