iNavier is an incompressible Navier Stokes Solver. iNavier works with general unstructured grids (polyhedral meshes are supported). Grid files should be in Fluent 6.x formats. iNavier uses SIMPLE algorithm for pressure velocity coupling. It also provides basic turbulence models and basic heat transfer models.

What is Dravvya?
Dravvya is GUI to help in setting up calculations with iNavier.

Who should use it?
The main target audience are students. iNavier tries to provide Navier Stokes solvers and frame work for users to add his/ her models concerning his/her research. This means user can concentrate on his research rather than spend hours trying to figure out Navier Stokes solvers. Others can also use this solver and easily modify it for their use.

Windows/Linux and parallelization and single processor issues.
Package contains 32 bit / 64 bit executable files and source code.  iNavier is written as openmp based program so it is a shared memory parallel code. If one wishes to create openmp based version he shall recompile it with suitable compiler.

iNavier does not use any external library so all one needs is a c++ compiler to compile this program. The source file contains automake based source. So on linux like shell:

make clean
make

should compile the program.

Can not run executable file!!

iNavierV2 is compiled with VS2005, VS2008. So in case there are some problems executing programs please download and install Visual Studio 2008  Redistributable Package from Microsoft site.

What is new from version 1?
Version 2 of iNavier mainly differs from Matrix solver's point. First version used additive corrective multigrid algorithm and second version uses much more robust smoothed aggregation multigrid. Due to this reason, second version is capable of handling large calculations without suffering from convergence problems.
