Why is CFD Difficult?

Of the 135 Symscape website visitors who voted in our latest poll, 37% cited mesh creation as the most difficult part of a Computational Fluid Dynamics (CFD) analysis. Configuring the geometry, deciding on physics and determining boundary conditions were clustered together as the next most difficult parts of CFD analysis. What is an engineer to do?

Caedium v4 Sneak Peek: CFD for 64-bit Mac OS X

The next release of the Caedium (v4) CFD software system will be fully 64-bit compatible with your Mac OS X computer. This means you will be able to run large simulations in Caedium that access all available memory under OS X v10.6 (Snow Leopard) and above.

Caedium v4 Sneak Peek: Rotating Vertical Axis Wind Turbine CFD Simulation

You will be able to simulate rotating wind turbines and mixers with the next release of the Caedium CFD software system. Caedium will support Moving Reference Frames (MRF), which is an efficient way to simulate rotating machinery.

Caedium CFD Software Helps High School Team To 2nd Fastest Time at the German F1 in Schools Finals

You may recall back in March that I covered how the high school team Fastcination won the South-East German F1 in Schools competition with help from Caedium. That regional win qualified Fastcination to compete for the 2012 German F1 in Schools title and now the results from that competition are in. Fastcination recorded the second fastest track time thanks to their low-drag CO2 dragster, aided by the Computational Fluid Dynamics (CFD) simulations performed by Caedium Professional.

Caedium v4 Sneak Peek: Tensile Membrane Structure Analysis

In the next version of Caedium you will be able to perform a CFD simulation of a tensile membrane structure and then export surface pressure coefficient (Cp) data for structural analysis in ixForten 4000. This exciting development will allow ixForten 4000 users to perform non-linear stress analysis to better determine membrane displacement with more precise wind pressure loads than previously available, leading to more cost efficient structures and supports.

Caedium v4 Sneak Peek: Centrifugal Compressor Passage CFD Simulation

We are still working on the next version of Caedium and thought it was time to share another update on Caedium v4 progress. This sneak peek highlights the new Caedium cyclic boundary condition along with other enhanced geometry tools that will enable CFD simulations of an idealized axisymmetric centrifugal compressor blade passage for instance.
