The Solution of Large Fluid Flow Models in ADINA, continued
Much improved solution times have been achieved in our new
In the September 28, 2004 News we showed two examples of large
fluid flow models solved with the new FCBI fluid flow elements and a
more efficient algebraic multi-grid (AMG) solver. We re-visit these problems here to show further solution times and show the solution of an additional problem.
The table below shows some further solution times obtained in double precision.

Important benchmarks in turbulence modeling are the flows in turning channels. This type of flow is common in engineering equipment such as turbomachinery and propulsion systems. We present the flow predictions and a direct comparison with experimental results obtained in the 120° turning channel depicted below.
Following is a graphical summary of the numerical results obtained using the 201,150 DOFs mesh compared to experimental data. The prediction of the pressure coefficient C
