What Free Software Programs do you like?

What Free Software Programs do you like?

(OP)
What free Mechanical Engineering-related software programs have you used? It could be software that you use for a very specific job-related purpose or for a very general one, but it *must* be absolutely free.

Thanks,

-Christine

RE: What Free Software Programs do you like?

Acrobat and any macros I think may be useful for SolidWorks, Excel or Word. Others I try to stay away from unless it is suggested from a reliable source.

IRstuff (Aerospace)
But why *must* it be free?  

Almost all of the engineering programs that are of any serious utility cost something, precisely because it's too expensive to develop for freeware.

The following site is interesting to browse through.

     http://www.freebyte.com/cad/

This page is part of that site.

     http://www.freebyte.com/cad/fea.htm#fea

The FEA page has a program (CADRE) that I had used, although I knew about it before I found the freebyte site.  I did eventually buy the full version, so I know at least one of these programs is good quality.  The rest, who knows?

Harvey Katmar, a respected member of this forum, has some good freeware available on his site www.katmarsoftware.com which I use often, both the turbine steam flow program, and the Uconeer units conversion program as well as the WASP limited use program, too (I guess it is still free).

Graham at www.graham-mfg.com has a free jet and LRVP sizing software called Vacworks II, which also has some good mollier programs, gas data, and conversions too.

The next one is not freeware in the sense that I can down load it, but it is free in the sense I can use the software, and it is the multi-effect evaporator sizing station at www.sugartech.co.za.  They have recently changed it to allow user selectable "K" values, and that makes it real nice.  There are also a couple other handy softwares on this site that I use from time to time.

There is a good turbine sizing tool that I use frequently at http://www.dresser-rand.com/steam/calc/main.asp and http://www.processassociates.com/process/tools.htm has some real good tools available at this site.

These come to mind right now.

There is an excellent pipe pressure drop calculator at http://www.xs4all.nl/%7Ekostermw/dP/ which I use regularly apart from the excellent conversion tool suggested by rmw.
Fellow member CARF has also got one excellent pipe pressure drop calculator at http://www.carf-engineering.com/

An steam properties calculator at http://www.chemicalogic.com/steamtab/downloads.htm

An elaborate cold storage calculation software at http://www.k-rp.com/calcrite/RTcalc1.htm

Good psychrometric property and refrigerant property calculators at http://www.pmilligan.net/pmtherm.htm

An excellent tool for R&AC at
http://www.et.dtu.dk/CoolPack/Download/Download.html

A duct sizer at http://www.mcquay.com/eprise/main/mcquaycom/designsolutions/designtools/MQC_designtools

I use all these tools daily, more or less. But keep in mind the fundamental rule with either free or expensive software. It is always garbage out when garbage in.

Christine74,

   What do you mean by "free software"?

   http://www.gnu.org ?

   Richard Stallman emphasizes his definition of "Free as in Freedom of Speech" as opposed to "Free Beer".

   Octave is a MathCAD clone:  http://www.octave.org/

   I am running Open Office on Linux at home, and it works fine.  The only problem I have had with it so far is importing Microsoft Word files generated from the Calendar wizard.  

   I would gladly pay for a good Free Software mechanical CAD package.  Pro/E is encrypting its files so that you can only access your data through their software.  You do not really own your data.

   Or did you must mean stuff that does not cost anything?

One of the best freeware programs I've ever used, and take everywhere I go, is one called Convert by Joshua Madison.

http://www.joshmadison.com/software/convert/

This is an incredibly simple, tiny and useful program....everytime I use it, I can hardly believe it was free.

RE: What Free Software Programs do you like?

If you are designing pipe networks then Epanet is fabulous. It can be used for extended period simulation, power determination and kinetic reactions (chlorine disinfection decay). Haestad methods use the same engine to drive thier Watercad.($15,000 for an unlimited license.)

It is free as it can be downloaded for nothing. However no software is free as you have to invest time and effort in learning & applying the program to real applications. Thats why I use AFT's Fathom because it easier & quicker to learn & apply than Epanet.On top of that I get "silver service" back up when I need it. Small cost to pay in license and support fees .

If you are a student then using the free stuff is good but dangerous. Not necessarily bug free and few have announcements of bug fixes.

RE: What Free Software Programs do you like?

Other than the unit conversion program mentioned previously, the finite element program FEAPPv is very useful when used in conjunction with another free program geompack for creating the mesh.

IntelliCAD is a pretty good free CAD program.  You should be able to find it easy enough on the web.

RE: What Free Software Programs do you like?

  IntelliCAD is not free. In the past, they had a fully working timed demo, but I don't know the current status of the timed demo.

MDSolids (Mechanics of Deformable Solids) 1.5 is a great free tool that can be googled, but 3.0 isn't very expensive.
http://www.mdsolids.com/
They have a 30 day demo for 3.0

Has anyone seen the X-CAD promo?  I've heard rumors that maybe Alibre is behind the mysterious marketing campaign. If so, that would be a decent package to receive for free.

Check it out: www.x-cad.net
