Finite Element Analysis

• A foam is one of the most difficult materials to simulate. Here is the example how the 3DExperience platform can capture behaviour of a foam cube under compression [GIF]

  A bit of hydrofoam compression from @oszohni for #SimulationFriday using @3DS_SIMULIA #3DEXPERIENCE Structural Simulation Engineer. Comming to a #SOLIDWORKS user near you soon pic.twitter.com/JvJxwRe9Tg

• A bulb, the invention of one of the greatest minds and thieves, analysed in one simulation. The analysis of bulb presents three modes of heat transfer (conduction, radiation and convection). [GIF]

  💡 Account for the 3 forms of heat transfer when simulating the free convection of argon in a light bulb: https://t.co/9fz5k9wfR2 pic.twitter.com/6sw5y0vxnx

Computational Fluid Dynamics

• Simulation of a swimming stingray - unbelievable! [MOV]
• A fluidized bed modelled using an open-source cfdemSolverPiso solver. [ MOV ]
• An article about wind farm CFD simulations using HPC. [ART]
• That is not the Dante’s hell. That is an outstanding visualisation of vorticity [PIC]

Computer Aided-Design

• Some news from Open-Source FreeCAD software [ART]

• List of free/almost-free CAD softwares [ART]

Engineering

• Why polymer stents failed more often comparing to those made from steel? The article shows how important is to perform appropriate fatigue tests. [ART]

• The residual stress in welds. I am not sure how it is done, but it looks nice! [PIC]
