Updated August 27, 2011 at 13:36 by wyldckat (Added a few notes)

This post is gathers information about OpenFOAM 2.0.x build times, using the gcc version that comes with Ubuntu 10.10, namely 4.4.5.

_____________ This was initially posted here: http://www.openfoam.com/mantisbt/view.php?id=256 _____________

Since I was curious about using N+1 processes, I've built OpenFOAM 3 times on my machine that has 8GB of DDR2 800MHz and one AMD 1055T X6, using Ubuntu 10.10 with its original gcc version:
  • 1st build with 6 processes;
  • 2nd

boiling in openFOAM

Posted August 12, 2011 at 16:06 by nimasam (OpenFOAM On Road)

i would like to review some works i have seen in openFOAM which involved boiling.
maybe the main work is related to professor Peter Stephan's group from darmstadt university.
they used the OpenFOAM solver (interfoam) as the basic solver and made new solver, first Bitan shu (Phase change with VOF) in paper "
PHASE CHANGE MODEL FOR TWO-PHASE FLUID FLOW BASED ON THE VOLUME OF FLUID METHOD" implemented welch method in "A Volume of Fluid Based Method for Fluid Flows with Phase...

Openfoam

Posted August 3, 2011 at 12:20 by mokcay

If anyone is interested in performing Openfoam analysis of a simple heat transfer problem for a fee please let me know. The problem:
Flow through a rectangular duct with cylindrical obstruction
Turbulent flow (use k-e model)
Initial Speed = > 3.5 m/s
Water only (single phase)
Fully developed velocity profile at inlet
Pressure outlet (0 gauge)
Steady state
Heat transfer = 10 W/ (all surfaces) m2

With this boundary condition, we have that:
  • If the velocity vector at the outlet points out of the domain, then the boundary condition will be of the Neumann type, ie, zeroGradient.
  • If the velocity vector points into the domain, then we can

<-- Related issues to ParaView with OpenFOAM - Fixes and solutions

This blog post is for those users who want to build ParaView 3.10.1 that comes with OpenFOAM's ThirdParty, version 2.0.0/x. It's based on a previous blog post of mine: Building ParaView 3.8.0 with custom Qt 4.6.3


In case you don't know, ParaView 3.10.1 that comes with OpenFOAM 2.0.0/x, during ParaView's compilation, it states that only Qt 4.6 is supported... oh well . So, in case your...
