This week’s This Week is brief because I’m not really here. But SimScale is running a contest, SU2 is registering for their developers meeting, and GridPro is animating structured grids. And we at Pointwise are seeking a mesh-loving CFD maven for our technical support team. (Thanks to Chi-Chen Kang on GrabCAD for the mouse.)
News and Jobs
- You have until 14 March to create your public project for entry into the SimScale Community Contest 2019. There will be cash prizes after judging for originality, complexity, relevance, and more. There’s even a social component because shares and likes count toward the judging. [“Show off your Sim-skills” W00t!]
- MSC’s Cradle CFD is now being distributed in Germany by Mantium CAE, developers of the MantiumFlow CFD software.
- The Hong Kong University of Science and Technology seeks a CFD research assistant in aerodynamics and sports engineering.
- Pointwise has an opening for a technical support engineer.
- Registration for the 4th Annual SU2 Developers Meeting is now live. The meeting will be in Villa Monastero, Varenna, Italy on 8-10 May 2019.
- CFMS shares their perspective on last year’s ICOSAHOM (International Conference on Spectral And High Order Methods). If air traffic is going to double over the next decade and a half our aircraft need to be more efficient. Can high-order methods get us the answers we need?
- Simulia’s PowerFLOW 6-2019 includes improved aerodynamics and soiling.
- Esgee released OverViz v2.3 for “plasma, fluid, electromagnetic, particle” simulations. [Wow, that’s a lot of stuff.]
Painting, Drawing, Meshing
When does a painting become a drawing or a drawing become a painting? Toward the end of his career, Jack Tworkov’s style moved from abstract expressionism to something more like geometric precisionism. Yet the color fields in Alternative IX below retain a painterly touch while the lines seem both fragile and rigid. The shapes’ tonal gradations unflatten the canvas in the third dimension and provide both heft and depth.
As a mesher what’s interesting to me is the structured grid that’s almost hidden in plain sight within the diagonals. The article linked to above describes this work as one in a series based on a Fibonacci sequence that Tworkov was using to create “identical structures but make each one a totally different painting experience (through) the color and the brushing.” The end effect for me are eyes that wander from the shapes to the lines and back again. The horizontal and vertical lines provide stability while the diagonal lines provide motion.
