Subject: Thermal Analysis on Macintosh (Summary)

This message contains a summary of answers I got on my question about
thermal analysis software for the Macintosh.

I would like to thank:

Tom Coradeschi      - tcora@Pica.Army.Mil
Mark Lankton        - lankton@pisces.colorado.edu
Jim Westfall        - westfall@pisces.colorado.edu
Matt X. Herbison    - mxh160@psu.edu

My original question was:

>A simple question:
>does somebody know if there is thermal analysis software available on
>the Macintosh? With thermal analysis software I mean a program which
>calculates temperatures and heat flows for 'nodes',from a mathematical
>model. For insiders, something like the SINDA (used in USA) or ESATAN
>(used in Europe) software.
>Because of the specialistic nature of this question, please reply by
>e-mail. I will summarize for the net.

Tom Coradeshi (Electric Armts Div, US Army ARDEC, Picatinny Arsenal, NJ)
answered:

>COSMOS/M does, via the "HSTAR" module. It's a product of Structural
>Research & Analysis Corp. I've played with a demo version and it isn't
>bad. They have a UK office at +44-865-711-011. Also, the US office is
>+310-452-2158. Hope this helps...

Mark Lankton from Laboratory for Atmospheric and Space Physics,
University of Colorado, provided the following info:

>We use COSMOS/M for both structural and thermal analysis on the Mac,
>and we have been pretty happy with it. U.S. phone number is 310-452-2158.
>I don't have the company address (Structural Research) in front of me
>but if you have trouble finding them please let me know and I can
>give you more information.

Jim Westfall (westfall@pisces.colorado.edu) pointed out that a version
of SINDA was available for the Mac:

Finally, I received very detailed information from Matt X. Herbison
(Apple Student Representative, Penn State University, mxh160@psu.edu):

>[Taken from The Redgate Macintosh Product Registry, it was the only one

>much, but I just wanted to show you what Redgate's Macintosh Product
>Directory (which has virtually all Mac products) contains under this topic.

>Engineer's Aide is an integrated process engineering package designed for
>chemical, mechanical and process engineers. Pipeline sizing determines pipeline
>diameter based on a target pressure drop or gives pressure drop for a given
>pipe diameter for gases or liquids. Pump/Fan/Compressor sizing determines

>determine the operative condition. Heat Exchanger sizing sizes shell and tube
>heat exchangers for either liquid, gas, condensing or boiling on either side
>without supplying thermal conductivity or heat transfer coefficients. Other
>equipment sizing includes orifices, venturis, flow nozzles, control valves and
>relief valves. The Conversion Calculator provides quick conversion of hundreds

>Specification Writer then provides custom specifications for purchasing any of
>the equipment sized in Engineer's Aide. An online fluid properties library
>determines fluid properties at any temperature or pressure and loads these
>values into any equipment sizing module. The Professional XL version contains
>the AIChE DIPPR database of 1,284 fluids with 34 properties.

>Sauna is a three-dimensional thermal analysis program with integrated color

>Sauna Modeling System provides even greater modeling power for tough thermal
