# Geometry simplification

Almost every geometry is at some level symmetric, which allows us to simplify it and by doing so **greatly decrease calculation time**.

Only part of the geometry can be simulated with symmetry boundary conditions, and it will still represent adequate results for the whole geometry.

## Delete repeating geometry

If your geometry consists of more than one identical workpiece-conductor system, select one to simulate and delete the others.

## Simulate only half

If you have geometry of linear symmetry, simulate only half of it and mirror results to represent the whole geometry.

## Cut out sector

If you have axial symmetric geometry, cut out and simulate one repeating sector of it, for example, one tooth from a whole gear, then revolve results to represent whole geometry.

## 3D to 2D

For revolved geometry there is no need for 3D simulation, simulate only plane slice from full geometry and revolve results to represent the whole geometry.
