HiFUN

Introduction

HiFUN: High Resolution Flow Solver on Unstructured meshes
Flow solver HiFUN, the primary product of SandI, is a general purpose industry standard flow solver for fluid flow analysis employing unstructured data based algorithms.HiFUN also serves as a research bed for exploring newer CFD algorithms. HiFUN is fine tuned to solve typical Aerospace applications and certain flow problems encountered in automotive industries. The code has been extensively used for solving a number of problems, over a wide range of Mach numbers, ranging from airship aerodynamics to aerodynamics of hypersonic vehicles.The algorithmic details of HiFUN and its validation are available at location http://sandi.co.in/v2/home/products.

Vendor: S & I Engineering Solutions Pvt. Ltd.
S & I Engineering Solutions (SandI: http://sandi.co.in) Pvt. Ltd. is a venture company started through an incubation program initiated by Society for Innovation and Development (SID), Indian Institute of Science (IISc), Bangalore. SandI is a technology driven company championing research and development of state-of-the-art CFD technologies with uncompromising quality standards for the benefit of the industry.

Modules :

  1. The module prehifun provides license for preprocessing grid data from .msh / (limited) cgns format to HiFUN’s native format.
  2. The modules hifun_core & hifun_process provide license for executing solver with required number of process-ranks
  3. The module posthifun provides license for writing grid and solution data in one of .vtk, .cgns or .plt (Tecplot) formats.

IMPORTANT:

HiFUN has preprocessing utility to convert mesh file obtained from grid generator in .msh or (limited) .cgns format to its native format. This utility needs to be executed in “serial” mode through GUI. For preprocessing mesh data, use Linux workstation class of front end system (X86-64 bit) available at SERC. The preprocessing utility typically requires 400 MB RAM per million finite volumes.  The solver execution, on the other hand, is in “parallel” mode and at present it is available on compute platform Tyrone at SERC. Typical memory required for solver is 800 MB per million finite volumes.
