Axisymmetry

Reduce a full 3D model with axisymmetric surfaces while accounting for imperfections.

This is useful in the pre-design thermal analysis of something like turbomachinery parts.

Since source solids may not be perfectly axisymmetric around a spin axis, this tool provides a way to imprint some details onto axisymmetric surfaces.

This will delimit region boundaries for the mesh. An algorithm (available in Volume Reduction) accounts for a volume reduction factor to capture the correct volume while spinning elements around an axis.

Example Use

In the model below, there are 6 bosses with pockets. The solid does not have a pure axis of revolution.
