The www.matosha.at platform is now open to the public, and we at Combustion Bay one e.U. are delighted to be able to offer it. 

Click & See an Example

In short, Matosha is digital plastiline!

 

 

Before you know it, you'll be creating amazingly beautiful 3D objects with stunning curves that you can print straight away using your 3D printer. Access to matosha is free. If you have any comments or suggestion, please send them to This email address is being protected from spambots. You need JavaScript enabled to view it..

You'll find a tutorial at the end of this article.

 

The subjects of “flow design” and “mathematics to shape” have been occupying us since we started working with additive manufacturing.

The “freedom of design” aspect extends the design possibilities for parts such as burners, particularly when there are very strong structural and thermal constraints, for limited lengths and volumes. This is where it becomes interesting to try new approaches other than straight holes or square grooves, with curves or volumes that have a mathematical definition.

 


'Flow Design & Mathematics to Shape' is an educational project designed to encourage designers to think inventively and boldly. This can be achieved by revisiting conventional solutions, such as diffusers, distributors and pipes, and enhancing them by adding a heat exchanger aspect, for example, or by inventing new solutions, as can be seen here and there on our site.

This software is used, for example, in Fabrice Giuliani's Privatissimum at the TU Graz: https://online.tugraz.at/tug_online/ee/ui/ca2/app/desktop/#/slc.tm.cp/student/courses/524269

The ultimate ambition of the 'Flow Design & Mathematics to Shape' approach is as follows:

  1. To provide a catalogue of unconventional design solutions that facilitate fluid transformation in thermal machines.
  2. To propose a range of simplified solution tools to estimate dimensionless numbers specific to the geometry of the part and the fluid passing through it (e.g. Reynolds, Prandtl and Nusselt numbers) and to define ideal operating ranges. This would be compared with the existing conventional approach, if one exists.
  3. The third aim is to automatically generate the shape of a part based on the desired transformation or combined transformations exerted on the fluid in the presence of specific mechanical or thermal constraints.

 

An international patent (A 50831/2024) has been filed for Matosha. We will be announcing its publication shortly.

Have fun with this programme. Recommend it to others! The more people who use it, the more convinced our investors will be! Help us develop it so that it becomes a standard tool for future mechanical engineers, architects and artists — all those who, like us, recognise the beauty in mathematical curves!

 

TUTORIAL MATOSHA

 

 

1) Visit www.matosha.at 

  • Select "View recent objects
  • Browse around to discover the new creations. If you like any of them, you can download them for free!

 

2) My first matosha : flate plate->  twisted plate -> boat helix

  • Select “Generate from Formula”
  • Fill in the "Title" and "Description" fields so that you can find, later, the objects you have created and that you particularly like using the "Search" function.
  • Formula: simply enter "x", the identity function.
  • Graphing mode : cartesian.
  • From : « -2 »
  • To : « 2 »
  • Outline (Thickness, equal in both normal and antinormal direction): 0.2
  • Extrusion mode: choose „along z“
  • Extrusion height: 9
  • Rotation/twist angle: 0
  • Dynamic scaling formula: 1
  • Click “Generate”

 

 


If you see Stanley Curbrik’s 2001 – A space Odyssey Monololith then CONGRATULATIONS YOU MADE YOUR FISRT IMPRESSIVE MOVE THROUGH MATOSHA

Did you know that the Monolyth’s dimensions are 1*4*9 that are the squares of 1,2,3?

·      

  • Now, click “Reshape”
  • Change nothing else but the “Rotation” where you enter the twist angle in radians: pi
  • Generate


If you’ve made it to twist the monolith then look for a bone somewhere around you, massacre everything around and then send the bone flying upwards in the air!!!!

 

  • When you are done you can “reshape” and test the magnification factor in the extrusion. Enter the function “Dynamic Scaling Formula: (x/9-0.5)^2+0.1“ 
  • Generate

 

And you get a propeller shape.

 

 

 

 

 

2) Test the polar coordinates : type « polar” in search and play with one of the examples!

  • Enjoy!
