MeshUp on Kickstarter
MeshUp is a project on Kickstarter seeking $25,000 to develop a modeling tool for 3D printing that works directly with meshes (i.e. faceted geometry). You have little over a week to contribute and help them reach their goal. [As I write this, their pledges total slightly over $17,000.]
Proposed features of MeshUp include the ability to merge meshes from multiple sources, the addition of microstructures to aid in the structural integrity of 3D printed parts, mesh repair, and guaranteed watertight output for 3D printing.
It is important to note that MeshUp would be a standalone version of Symvol, a plugin for Rhino that has many of the same capabilities.

- Robert McNeel & Associates, the Rhino3D people, announced the availability of openNURBS 5, their free toolkit for 3D geometry exchange using the 3DM file format.
- When it comes to faceted geometry data exchange, the simplistic STL format is king. OpenRP was proposed as an improvement and now along comes AMF.
- PTC is offering Mathcad Express for free.
- FDS, the Fire Dynamics Simulator, is a LES code for low-speed flows especially those with smoke and heat transport from fires. Version 6 is ready for beta testing.
- Visualising Data presents their best of the visualization web list for September 2012.
- NAFEMS is offering a 2-day course on Introduction to CFD Analysis: Theory and Applications on 26-27 Nov 2012 in Wiesbaden, Germany.
- The next 3D Collaboration and Interoperability Conference (3DCIC), dedicated to fostering improvements in the exchange of 3D design geometry, will be held 21-23 May 2013 in Colorado Springs.
- The 1st Symposium on OpenFOAM in Wind Energy will be held on 20-21 March 2013 in Oldenburg, Germany. [The abstract deadline has already passed.]
Applications and Business
- Cadlog Srl was announced as the Italian distributor of Mentor Graphic’s CFD products.
- Siemens PLM will acquire LMS International.
- How reversible is fluid mixing? In this case, very. [This is an old video that you’ve probably already seen.]
- Researchers are using CFD to study motorcycle aerodynamics. This is not any old motorcycle – it’s Jet Reaction on which a rider will attempt a 425 mph speed record.
Morphometric Integrity of Cookie Dough
This is science you can sink your teeth into. [Poor joke but it had to be written.] I suppose within CFD only a mesh generator would be interested in the morphology of various materials and shapes so this study may have limited interest from that standpoint. However, in a beautifully illustrated study it is made clear that cookie dough loses its morphological integrity at a temperature of about 375 deg. F with about a 100% area increase and a 25% increase in circularity.
Do CFDers Use CAD?
On ENGINEERING.com, Chad Jackson writes about a post on LinkedIn in which the poster opines that having engineers use CAD software to make drawings was not an effective use of their time. Back in the day, draftsmen [draftspeople?] would create drawings and would cost the company much less than an engineer. Now engineers get paid to do CAD.
Geometry, usually from CAD, is central to CFD. And at the same time it’s hugely problematic. For a while now I’ve been ruminating on a geometry-centric post here. My experience is that most CFDers don’t use CAD. Do you agree? If you had to, would it be a waste of your time?

Water Droplets + Typography = Lumen Type
Inspired by seeing the world through raindrop covered eyeglasses, artist and designer Ruslan Khasonov created Lumen Type, a typeface made by carefully placing water droplets on a mirror and photographing them under various types of illumination. Be sure to watch the video.
