Finite Element Analysis

• Hail can be very dangerous for car owner. The results show how easily tiny particles destroy our vehicles [GIF]

• OpenFOAM allows for avalanche modelling. Quite cool feature, I am wondering when it is needed to perform this kind of simulation [VID]

• When someone asks me what is the difference between Euler and Lagrange mesh, I am always struggling to rembember which is which. This article explains it very well [ART]

• A good book for all Abaqus users and Python maniacs [PDF]

Computational Fluid Dynamics

• Great model of pedalling cyclist in STAR-CCM+. “Cycling is probably only one of two sports (the other being sailing) where aerodynamic performance directly impacts the athlete. So much so that at 50km/h 90% of the energy loss is related to aerodynamic drag.” - from Siemens blog. I knew that aerodynamics has huge impact on cycling, but I didn’t think it is so huge! [VID]

• Nicely looking fluid-structure interaction example. Although, for sure it is not numericaly simple! [ART]

Other types of simulation

• Agricultural application of Discrete Element Method. Here, coupled with Multi-Body Dynamics [VID]

• Another code, still DEM. This time DEM is used to model grass mowing. The analysis is great, but I wouldn’t buy this mover - too much grass going everywhere [GIF]

• The last DEM usage - coupled with CFD code to model pneumatic systems [VID]

• Anyone thought about modelling birds using ballons with water? Some smart people did think [PIC]

Engineering

• I am more like a Marvel fan, but this Flash mask created in SolidWorks is really good. [VID]

• Keep on rollin’ baby! [GIF]

• The article explains what caused the rapid sinking of the Titanic [ART]
