FLUENT - Workaround for pathline plots with unacceptable color distribution (insufficient number of colors to represent all pathlines tracked)


If you create a pathline plot and use Particle ID as the "Color By" variable, you may get an unacceptable distribution of colors, particularly if you are releasing the particles from...

FLUENT - Tips to workaround the issue of not being able to play an mpeg file created by Fluent software (using mpeg_encode) on Windows NT / 2000 platforms


When you create a mpeg animation from Fluent software (which uses the Berkeley mpeg encoder "mpeg_encode"), this sometimes cannot be played by the Windows media player (standard mpeg...

FLUENT - Suggestions for tools to animate unsteady results from FLUENT on the Windows platform


The FLUENT distribution does include some software tools in the contrib directory to animate results on UNIX and LINUX systems. However, these utilities are not available for Windows. Any...

FLUENT V6 - how to workaround the "invalid window id" error when you have 20 or more monitors defined with your run


If you define 20 or more monitors in your FLUENT run, you may see a "Invalid Window ID" error when you begin the calculation.<br>The problem lies in a limit of 20 windows that...

FLUENT - A possible procedure for modeling the soaking condition in automotive underhood simulations


The soaking condition would be the most challenging phase of the underhood simulation. Natural convection problems in general are highly unstable, because of the non-linearity due to strong...

FLUENT - Two common errors when using the planar conduction model (floating point exception or MPI error) and tips to address the underlying issues


Most of the issues with planar conduction in parallel mode are not actually due to parallel.<br>There are two other possible causes:<br><br>I) If one gets floating point...

FLUENT - a possible approach to model heat exchangers if fin effectiveness or efficiency is known.


Imagine a fin-to-fin heat exchanger. Imagine two ducts connected to each other by sharing a face wall-1. In the actual model this wall would have fins on both sides. Let assume wall-1 is facing...

FLUENT V5 - Sample User-defined Function (UDF) to determine flow direction through interior faces in the domain


The domain has many interiors in order to know where the flow goes (in or out from some region). The objective is to determine flow rate and direction through each of them. Unfortunately, flux...
