fluidyn MP-NS

•  A general purpose second generation Computational Fluid Dynamics (CFD) Software Package

• Simulation of internal or external fluid flows in and around geometrical configurations of practical importance

• 2nd or 3rd order high precision Numerical Schemes

• Higher Order Numerical Schemes ensure capturing of discontinuities and steep gradients in flow field

• Solves incompressible or compressible, viscous or inviscid, laminar or turbulent flows with / without gravitational effect

• Multi-Block Structured or Unstructured or hybrid stationary/moving mesh in Finite Volume

• Modular Package consists of pre-processor, multiple solvers and post-processor 

fluidyn MP-NS Comprises of a GUI and Three  Batch Solvers Namely 

• NSTVD à Density Based Solver using Flux Splitting TV

• NSNT à Pressure Based Solver

• NSMBàMulti block Solver

Flux Splitting TVD Solver (NS) 

• Unstructured hybrid mesh (tetra, hexa, pyramid, prism)

• Flux Vector Splitting (van leer, AUSM, HLLC)

• Flux Difference Splitting (Roe)

• Preconditioned Roe for incompressible flows

Pressure-based SIMPLE Solver (NSNT)

• Polyhedral hybrid mesh (any number of sides)

• Blended Schemes: CDS, Gamma, TVD (van Leer smooth, van Albada, MinMod, Super-B, SMART, UMIST, van Leer MUSCL, …)

• Upto 3rd order accuracy in Space

• Unsteady Cases: Euler implicit, 3-time-level schemes

• Multi-step robust SIMPLE for pressure computation on non-orthogonal mesh: one solver for flows at all speeds
