In the world of Computational Fluid Dynamics (CFD), we have long been “trapped” by the mesh. Whether you are simulating the splash of a breaking wave or the complex rotation inside a centrifugal pump, the mesh is often the Read more
When it comes to simulating the movement of matter, there isn’t a “one size fits all” approach. If you are modeling a landslide, a breaking wave, or a conveyor belt filled with minerals, the physics engine you choose determines Read more
In complex mechanical simulations, maintaining an accurate mesh throughout a non-linear evolution is critical. This guide explores how to implement automatic mesh adaptation using the MACR_ADAP_MAIL macro in code_aster, specifically for cases involving the STAT_NON_LINE solver. 1. Overview of Read more
Structural stability is paramount in design. While static analysis helps us understand stress and deformation, it doesn’t always tell the whole story. A slender column, perfectly safe under a static load, can suddenly collapse due to buckling when that Read more
In the realm of high-performance building physics, steady-state calculations (like simple U-values) often fail to capture the reality of how a building behaves under fluctuating external temperatures. To design structures that maintain comfort while minimizing HVAC loads, engineers must Read more
Fires aren’t all created equal. In the world of fire protection engineering, understanding the nature of the fuel is the first step toward stopping it. This is where ISO 3941 comes in—it’s the international standard that categorizes fires into Read more
Handling Particle Temperature Errors in FDS: A Troubleshooting Guide If you are running a fire simulation involving sprinklers, water mist, or fuel sprays, you might eventually run into a specific pair of warnings in your .out file: WARNING Delta Read more
In the world of OpenFOAM, generating a high-quality mesh is often 80% of the battle. While snappyHexMesh is incredibly powerful for snapping to complex geometries, getting those elusive, crisp boundary layers can feel like more of an art than Read more
For Fire Safety Engineers, the transition from complex fluid dynamics simulations to regulatory compliance documentation is often the most time-consuming phase of a project. Performing FDS (Fire Dynamics Simulator) analyses requires immense computational power, but the ultimate goal is Read more
As the engineering world moves toward more complex, interconnected designs, the need for robust multi-physics simulation tools has never been greater. While commercial software often comes with a hefty price tag, Elmer FEM stands out as a powerful, open-source Read more
