Fidelity and accuracy are critical in computational fluid dynamics (CFD) simulation. After all, physical prototyping and testing can only be reduced if one can expect accurate simulation results.
But up to now, high fidelity, high accuracy results have come with a price.
Complex, realistic geometries have required hours of manual effort to clean up the model and prepare the mesh. Users have been tempted to cut corners and take shortcuts that speed up prep but take a toll on accuracy and fidelity. There is no way of knowing just how those inaccuracies skew results, putting any recommendations in doubt.
This paper discusses recently developments in ANSYS to tackle this challenge.
