Poprad, Slovakia…
u might already noticed.
Second great thing is that is quite fast, precise and versatile (for this kind of things); also is way OPEN (meaning you can attach and or interface it with almost anything you can imagine, meaning hardware, and other sw components, etc (like a CNC machine (additive manufacturing toys..) or any sw like C# component)) making a GREAT HUGE difference with almost any other CAD (and CAM sw i must say)
i made a simple fully functional CAM component - highly powerful ! - in a couple of days...
also tested an arduino interface (meaning control over almost any elctronic device out there)... in a matter of hours...
and saw and can easily think about lots and lots of extremely cool usages of this great tool in almost any area ...
So that's why i would suggest - and will do something about for - it (or similar tools) to be teached at first stages of education !
But power comes with responsability. and is far better exploited when your are smart ;)
I think people that uses GH will be n-times as good when they don`t forget manufacturing.
This includes teachers btw....
Interesting thing to account is that all things that GH is great at (a LOT) means reducing dramatically the time spent to model almost anything...
But usually the purpose (unless the objective is just learning or doing some kind of virtual art (both legal stuff btw...;) but guess it might not be your case now and after graduating..)) is to end up by actually building some real 3D stuff...
So what Joseph is poining is key...
If you have a good teacher.. i guess it should pay more and more attention not just at your gh skills but rather the way in which you use the power, versatility and extra time gh (and additive manufacturing tech) saves, to think about how to design the stuff focusing on the ultimately relevant stuff...
optimisation...
So..
I would say that any heat interchanger like the one involved in your thesis, has to deal with fluids.. have to account for some sort of life span (involving cheaper an ideally no maintenance needed along its life...), and of course also critical the costs of manufacturing.
so... be the best one...
use GH smartly ! ie...
account for different profile paths for oil and water.. they're different fluids meaning they have different specific heat, viscosity, blah... and so... they might not even traverse the interchanger at same flow ratio, etc.
So... maybe you want to start by reshaping the grid... (parametrically...!) so you can arbitrarily and dynamically modify and get to see interactively in your definition the areas ratio of sections so as to finaly get to set the "ideal" (meainng optimum) relative areas (sections) ratio of oil to water paths... (or whatever other fluids could be !), and the material also...
Secondly you might also consider that triangles might not be well suited for the conduit sections because are not the best shape to carry most fluids... (hoses are of circular sections...worst case are kinda rectangular with rounded corners..;) not only because the're easy to manufacture but also because they minimise (optimize) flowing energy losses AND are less prone to (ie salt or debree deposits in the interior) ). so think about rounded shapes, of if you want some regular polygons stuff but 5 or more faces...kinda circular...got it ?
I love bees by the way..
and if you happen to need more interchange area (obviously another (and probably the #1 key one) figure you should be displaying interactively in your definition ) you can always add some more extrusion length...
third... the twisting stuff is cool... (artistically ;)) but i 100% agree with Joseph is far likely to involve higer costs for manufacturing with no clear benefit on surface maximization... and most probably some other losses in added friction to the flow of fluids (meaning higher costs for pumping, etc...)...
fourth...
consider the area, (then the volume!) of the "building material"... you should optimise that too ! so this could be another one of your interactive displays...
in this case... you not only can see optimisation by reducing the amount of materials to build your interchanger...
but you can also notice that if the "building tech" involves the well and common additive manufacturing process of extrusion deposits... that surface area, and that extrusion length, meaning volume and cost of raw material, also mean TIME to manufacture... and i guess you teacher will find good for you to consider and mention that one too...
fifth...
finally (for now hehe), and globally most important in the short term :)
if the objective of yor teacher is for you just to learn GH and impress him and the rest of the world then, ok, do the twist the swirl and imagine all kind of sea star and or ondulated conduit sections (maybe some recursive forms (fractals...) like snowflakes... or any n-arms (mutant !) starfishes shapes) but make sure you first get to know and validate what it will be the objectives of your evaluator...
.. in the near end this is all about passing your thesis while learning GH while having fun.. isn't it ?
go for it and best of luck !
ps: for the mid and long term.. some day take a look at linear optimisaton if you already didn't.
i think GH is a great tool to try out some linear optimisation stuff directly linking geometry related figures (areas, volumes...) along with costs figures !...
I haven't seen anything like that yet (but since i'm only a few months old in gh, i think is likely to already be something or this stuff out there. )
If not... well you can always be the first !
(and this particular case of your thesis is a great example (few key variables) to try out "automatic optimisation")
https://en.wikipedia.org/wiki/Simplex_algorithm
that... by the way...has lots to do with spatial geometry...

k questions during the workshop but I will be using Ladybug example files which you can download from the Ladybug group page so you can follow along with the workshop. You can send me your questions later.
The workshop is a part of the Environmental Design Studio for the students of the Master in Environmental Building Design (MEBD) program at PennDesign.
Tentative outline:
Getting Started: (epw file, 3d charts, conditional statements)
Wind analysis: (windrose, conditional statement > potential for natural ventilation)
Sky + Radiation: (radiation rose, sky dome)
Sunpath + Shading design: (hourly data overlay, conditional statement)
Radiation, Sunlight hours analysis (roof design, optimum orientation)
In case we have time we will also cover one example about:

significant step towards Grasshopper 1.0
Since there is so much new stuff in 0.9 I feel I ought to caution you to not switch to the new version without carefully considering the pros and cons. There will most likely be serious bugs that our internal round of testing did not find, some of these bugs may prove so crippling to your work that you will not be able to use 0.9 until they are straightened out. You can of course always download the previous version, but you may not be able to open files made with 0.9 on earlier versions. So be careful to not overwrite old files unless you're certain that the new release is something you're happy with.
Grasshopper 0.9.0005 can be downloaded from the usual place. Note that you must have a recent version of the Microsoft C++ runtimes on your machine. See this FAQ post for more details.
Since 0.8 there have been three major changes, hopefully all for the better:
Clusters
AutoSave
DataMatching
Clusters have been rewritten. They are not done yet but done enough for initial testing. I wrote down some useful details about what's new, you can read them here.
AutoSave has been rewritten and works in a fundamentally different fashion. The goal was both to remove autosave files from visible locations and to provide a more robust recovery system in case things go awry. If you want to know more, some details are available here.
Data Matching has been tuned a bit. Some bugs have been solved and hopefully no new bugs have been introduced. Datatrees should now grow complex less rapidly in certain cases. Again, some nitty-gritty details can be found here. Due to the changes it is quite likely that a lot of old files that rely on a specific data-tree layout will no longer work. This is a necessary evil in my opinion, but be warned that this may cause significant delays while switching over to 0.9
Here follows a (not exhaustive) list of changes since 0.8.0066.
Important Changes:
Data Trees are now constructed differently in some cases, this may break files that depend on specific data tree layouts.
File format forwards compatibility has been broken. You may not be able to open files saved with 0.9.0005 on earlier versions.
Parts of the Grasshopper SDK have been broken. You may not be able to load GHA files compiled for earlier versions.
Component Data Matching menu items are no longer available, please use the dedicated matching components.
Components with one-shot option input parameters have almost all been replaced with components that have options in the menu.
AutoSaving behaviour has been redesigned to hopefully provide less fragile protection against data-loss.
We've had some serious crashes with the [Cloud Display] component. In some cases even Blue-screen crashes. Be sure all your work is saved (not just in Rhino) when you use [Cloud Display] component.
New features:
2600+ LolCats, but I stopped adding them as ICanHasCheezBurger is no longer fun.
Standard windows tooltips will be on screen for a longer period than the Windows default of five seconds.
Grasshopper will now load GHA files that are part of RHI installer packages.

Bug fixes:
Components with Preview=Off would not display in selected only mode, this is fixed.
Instantiating number sliders via the popup box would not work if the first number was negative, this is fixed.
Copy to Windows Clipboard would not fail gracefully on error, this is fixed.
Interpolate Curve component would not warn on invalid degrees, this is fixed.
Knob menu control was not correctly initialized, this is fixed.

Editor window would not reflect saved/unsaved state of the loaded document, this is fixed.
MultiDimensional Slider would not undo on grip drags, this is fixed.
Image Sampler would not behave nicely when an image file went missing sometimes, this is fixed.

Text Panels would not display a scrollbar for local text, this is fixed.
Vector Display component would remain visible after disconnecting, this is fixed.
Vector Display Ex component would remain visible after disconnecting, this is fixed.
Adding or removing output parameters from VB/C# script would not update the script, this is fixed.
A CCX overlap intersection would sometimes result in erroneous parameters, this is fixed.
The tooltip over the abort icon would not show, this is fixed.
The canvas wouldn't always redraw when the solver was locked, this is fixed.
Transform Parameter Set menu items did nothing, they are now greyed out.
Occlusion Component would always return a null topology, this is fixed.
Group crossing selection would fail on concave group outlines, this is fixed.
Transform input parameters on components would have an empty transform by default, this is fixed.
Sweeps sometimes outputted surfaces with internal kinks, this is fixed.
Output parameters that output lists now have tooltip suffixes indicating them as such.
VB/C# script with no input parameter failed to run, this is fixed.
Tooltip title text for components and parameters was basically unreadable, this is fixed.
Transform component claimed "Mirrored Geometry" as an output, this is fixed.

Referenced geometry which no longer exists in Rhino is now stored as a null rather than invalid item.
There will probably be a flurry of releases following this one as bug-reports and wishes come in. If you feel skittish about diving into a dangerous beta feel free to wait until 0.9 has settled a bit.
Enjoy!
