CFD Visualization Helps Protect Integrity of Buildings, Bridges, and Ships

November 2010 When Adam Hapij, senior associate at the structural engineering firm Weidlinger Associates, recently visited his son’s kindergarten class, he tried to explain what he does in a way a 5-year-old could comprehend. In the end, he simply said, “I protect people.” Indeed, at its very core, Hapij’s job is to protect people. Since Weidlinger opened for business more than half a century ago, the company has designed all […]

Tecplot helps utility researchers visualize magnetic fields

Contributed by Sylvain Gravel Hydro-Québec The Challenge: Accurately Visualizing Magnetic Flux Density In working with electrical power production and distribution, a key problem faced is being able to see the unseen – in other words, how does one view invisible electrical and magnetic forces at play? Hydro-Québec needed to be able to see magnetic flux density near a distribution power line, which is essentially understanding the power flow in the […]

Plot of the month: Melbourne cricket ground redevelopment

Contributed by Eric Jal, Sr. Engineer, Energy Div. Connell Wagner, Melbourne, Australia Ventilation is a key design factor for the new Melbourne Cricket Ground (MCG). Using PHOENICS to optimize the design, CFD and Tecplot have been used to analyze air movement within the building and in external areas. In this image we see relative changes in air movement patterns across the pitch due to the construction of the new Northern […]

Plot of the month: Wave interaction with a tension leg platform

Contributed by Dr. Sundar Prasad, Senior Analyst, Coastal & Ocean Engineering Group Sandwell Engineering, Inc., Vancouver, B.C. The crest of a wave reaches the forward legs of a platform in the figure below. Data visualization is a key component in post processing results from Sandwell’s numerical models. Tecplot quickly allows them to represent large quantities of data in a form that can be understood easily. This layout shows how the […]
