desc.grid.LinearGrid.sym

property LinearGrid.symSource

True for poloidal up/down symmetry, False otherwise.

Whether the poloidal domain of this grid is truncated to [0, π] ⊂ [0, 2π) to take advantage of poloidal up/down symmetry, which is a stronger condition than stellarator symmetry. Still, when stellarator symmetry exists, flux surface integrals and volume integrals are invariant to this truncation.
