Mesh adaptation has improved solution speed

and quality in many applications since

introduced in Simulation CFD version 2013.

We have continued to improve adaptation and

extend the model to cover more applications.

In version 2015 we are adding:

Free shear layers

Compressible shocks

Heat producing parts

Mesh Adaption Improvements

Often times users need to specify BC

with gradient. This allows for a more

accurate representation of inlet


Applications include

Models where inlet conditions need

to match physical measurements

Wind shear applications

Spatially Variable Boundary Condition

Wind tunnel CFD

Consistent Design Study Bar collapse/expand


Shell element resistance heating

Expanded import options

- STEP, CATIA, IGES, Rhino, Siemens JT

SpaceClaim CAD launcher

Revised Inventor launcher presentation

Anisotropic blending available within UI

Wall roughness model for SST

Cloud and remote solve robustness

Simulation CFD pressure mapping to Simulation
