 - Fixed an issue where the ridge feature in spherical geometries for both the half space cooling and plate cooling models gave a discontinuous spreading center when crossing longitudes at intervals of 90 degrees. \[Daniel Douglas; 2024-01-22; [#520](github.com/GeodynamicWorldBuilder/WorldBuilder/pull/520),[#518](github.com/GeodynamicWorldBuilder/WorldBuilder/issues/518)\]
 - In some cases the bezier curve closest_point_on_curve_segment function would include a half circle around the end point(s) as part of a slab/fault. \[Menno Fraters, reported by Daniel Douglas;2023-12-07; [#522](https://github.com/GeodynamicWorldBuilder/WorldBuilder/issues/522) and [#523](https://github.com/GeodynamicWorldBuilder/WorldBuilder/pull/523)\]
 - In some cases the fault feature would not recognize points as inside the fault if they were exactly on the fault line. This is fixed now. \[Rene Gassmoeller; 2024-02-16; [#640](https://github.com/GeodynamicWorldBuilder/WorldBuilder/pull/640)\]
+- The input name for the annulus was misspelled as `anullus`. This is now fixed. \[Menno Fraters and Juliane Dannberg; 2024-02-22; [#539](https://github.com/GeodynamicWorldBuilder/WorldBuilder/issues/539) and [#666](https://github.com/GeodynamicWorldBuilder/WorldBuilder/issues/666)]

 A grid file consists of a number of parameters. Each parameter should start with a name (no spaces) followed by an equal sign, followed by the value. The available parameters are:
 
-1. `grid_type`: Options are `cartesian`, `sphere`, `chunk` and `anullus`. 
+1. `grid_type`: Options are `cartesian`, `sphere`, `chunk` and `annulus`. 
 2. `dim`: dimension, either 2 or 3.
 3. `composition`: how many compositions
 4. `vtu_output_format`: Either `ASCII` for readable output or `RawBinaryCompressed` for compressed output.
