CFD Modelling-Natural and Mechanical Ventilation
CFD Modelling-Natural and Mechanical Ventilation
(OP)
My company wants to get into CFD modelling and the modelling of natural and forced airflow patterns for ventilation design. Many clients in the UK want this so they can predict how well the natural or mechanical ventilation systems will work.
There appear to be a number of CFD programmes about... (all fairly expensive). Has anybody got experience of the various software options and perhaps point me in the right direction.
The systems need to be well proven and fairly easy to use.
PS (Metric units prefered)
Our budget for software would be about £4000 to £5000. (or am i being a bit optimistic)

Incidentally, if anyones used one of these programmes, how accurate are the results? Have real life comparisons been documented?

The interface is designed to work you though model creation (assuming the user doesn't have a large CFD background) - the CFD mesh is created automatically allowing the user to specify as much or as little as possible... The solution post-processing isn't quite as automated but with the training included in the software you should be all set.
I was able to generate results fast and accurately (the modeling efforts were benchmarked to test data). I found for these types of analysis it to be much more efficient then using the it's big brother "FLUENT".
the local fluent office would be more then willing to work through a demo problem with you...
It should be noted although the software is a "lite" version of the "big brother" depending it could still require pretty good hardware requirements depending the size of your spaces...
