So since my in conclusion post, I've acquired a novel 13" laptop to supersede the expert erstwhile asus eee 701, I needed a small, fast together with expert pc for some of my applied scientific discipline work.
Just inwards brusk lines the PC is an Acer Travelmate 8371, together with Linux Mint Debian Edition runs really smooth.... solely 1 affair does non piece of work at all, together with that is the fingerprint reader, which I don't attention at all.. One of the most of import things for me inwards laptops is battery (6 hours) together with suspend (all ACPI events plant out of the box. Even the intel wireless bill of fare piece of work without problems...So I'm really pleased amongst this footling together with robust machine...
So, dorsum on the postal service title.... As I acquired this machine mainly for work, I started filling it upwards amongst software that I usage on my 24-hour interval to 24-hour interval piece of work (I piece of work for a Portuguese large HVAC contractor, together with ain my ain consulting company), together with equally y'all may think, I pass a lot of my fourth dimension working...
So, starting from the basis...
1 - My desktop, the forest one, is total of interesting stuff, drawings, notes, specifications, catalogs, databooks, cloth samples, a existent mess... then sometimes finding the estimator is hard... then I usage the most powerful estimator on Linux... And that is Qcalculate (check the repositories)... Imagine this mutual province of affairs for me, equally manufacturers that I piece of work amongst approximately the globe all piece of work inwards dissimilar units....
Pressure driblet calculation:
- Heat Exchanger - 40kPa
- three means valve - 1 bar
- Pipes - 2 mca
etc etc...
So, ordinarily to produce this calculation together with getting the upshot inwards bar, for instance, or y'all guide maintain a expert datasheet, or y'all usage qcalculate... exactly past times typing....
"(40kPa+1bar+2mca) to bar" y'all larn the fine response "1,5960828 bars", banknote that the mca (column of H2O meters, really used here) is non 1 of supplied conversions, but y'all tin terminate plan whatever conversion y'all want, Qalculate has a large database of units, currency conversion (automatic update of telephone substitution rates), math functions, variables, phisycal constants, etc, etc.... It has capability of solving equations, plot functions, a lot of interesting materials for y'all engineers to explore...
2 - So, inwards the CAD area, I've written a lot most this, but a listing of the ameliorate ones available native:
- Bricscad (Comercial, Autocad Clone),
- Varicad (3D based, for me its the best CAD software available for Linux)
- Draftsight (free, Autocad Clone, but no Autolisp),
- Ares Commander (the begetter of Draftsight, comercial, total featured),
- Freecad (very good, audio promissing),
- QCAD (released a novel version, looks a lot ameliorate together with is cheap)
- Medusa4 (free personal version, really expert commercial software)
And y'all guide maintain a lot of others, but for some argue to me are non worthy to endure inwards this list, but hither is a link to an updated regularly listing of CAD software on Linux http://www.tech-edv.co.at/sl.php?058010. I recommend this list, I larn at that spot to accept a hold off at the tidings really often... (thank you)
Remember that I'm writing most software that I actually used or usage for production purposes, then my opinions are non from a inexperienced soul on this type of software.... I've been working amongst cad software since 1996 :)....
3 - On discover three nosotros guide maintain a non native Linux software, but equally they back upwards Linux through vino (and I've bought a license, cough, cough).... I'm talking most SF Pressure Drop 7.0 (7.15 version don't work) a total bundle software to calculate clit per unit of measurement area driblet inwards pipes. It has a total database of pipes, accessories, valves, etc, etc, it also has a total database of fluids (liquids together with gases) amongst all the temperature together with clit per unit of measurement area properties, states, etc, etc. I also allows y'all to calculate pumps, reservoirs empty times, economical pipage diameter, etc etc.. It is really consummate together with deserves a look.
I complete this small-scale review amongst a screenshot...
4 - I piece of work amongst a lot of PDF files from OEM's, clients, tables from books, etc, etc, etc... together with a lot of times I've to markup those to acquaint to consultants, or exactly to banknote something useful... So I'm talking most PDF annotation together with manipulation.
I piece of work amongst 2 software:
For Annotation I usage Xournal (it's on every repository), together with it allows me to produce something like...
It has a shape recognizer that allow y'all to produce direct lines, together with squares, rectangles, circles, etc, etc... Files are saved amongst .xoj extension, together with y'all tin terminate export them to PDF amongst the annotations, really useful, equally it saves a lot of unnecessary printing...
For manipulation I usage PDFChain (in repositories also). In the past times I used PDFSam, but it is slower to piece of work amongst due to the interface... So PDFChain allow me to crop, rotate, separate together with merge PDF's.
5 - On discover v is Elmer+Gmsh (both on Debian Testing repositories), the software I usage to brand CFD calculations. I've started using them recently, together with equally I'm non really familiar, I'll accept the selection to exactly verbalise most the tricks to brand them piece of work amongst DXF files for complex layouts, together with the residue of physical together with equation materials y'all volition guide maintain to accept a hold off at the software tutorials.... (beside that I'm a lot of rusty inwards finite chemical component calculation)
So inwards the commencement fourth dimension y'all depict something on draftsight for instance.... Save it equally dxf.... Import it amongst Gmsh.... Create the mesh... together with relieve mesh equally "Mesh - Gmsh MSH (*.msh)" guide version 2 ASCII together with "Save All".
Now the play tricks (that took me a all black to figure this out), opened upwards the generated file amongst a text editor together with exactly supersede the "." (dots) amongst "," (commas), somehow Elmer mess things up...
Import mesh into Elmer, model the problem, together with inwards the in conclusion y'all tin terminate guide maintain a upshot similar this...
The inwards a higher identify picture represents the air speed within a HVAC plenum, it was exactly a test, equally the employment was non really good formulated, but y'all tin terminate larn a thought of what this is capable...
6 - Other software that worth a hold off (in the repositories)
- Crunchbang - a less powerful estimator the qalculate
- Octave - Matlab Clone
- PSPP - SPSS clone (statistics) - Never tried it
- Electric - Draw electrical Schematics (I've tried but I'm a mech engineer... )
So this is it for now.... together with equally I'm brusk on time, experience complimentary to follow me on this social networks:
Twitter - @ECA_Engenharia
Identi.ca - @pirolocito
We tin terminate guide maintain a squeamish verbalise on a brusk spare time... And remember, linux is easy.... Sumber http://linuxmadeasy.blogspot.com/
