 For these reasons, HOHQMesh was developed to generate all-quadrilateral and extruded hexahedral meshes suitable for use with spectral element methods. HOHQMesh is a direct quadrilateral mesher, which generates quadrilateral elements by the subdivision method of Schneiders [@schneiders2000algorithms] rather than indirectly from a triangular mesh or by curving a low order mesh. It also sizes and curves the elements based on the length scales in the model, rather than try to modify an existing low order mesh.

 HOHQMesh is designed to require minimal input from the user through the use of a control file. The model defines the geometry in terms of an outer and inner boundary curves.

 In 1959 the Malpasset dam in France failed and flooded the Reyran river valley down to the Mediterranean sea [@hervouet1999malpasset],[@goutal1999malpasset]. Fig \ref{fig:Total} shows a mesh with 2392 fourth order elements generated by HOHQMesh in 0.44s on an Apple MacBook Pro with a 2.3 GHz Quad-Core Intel
 i7. A zoom of the western portion of the mesh is shown in Fig. \ref{fig:zoom}. The geometry model consists only of an outer boundary, which was specified as a cubic spline, and no inner boundaries. Fig. \ref{fig:WaterHeight} shows a spectral element computation of the water heights using the mesh of Fig. \ref{fig:Total} in the package Trixi.jl [@schlottkelakemper2021purely].

 Special purpose quad/hex spectral element grid generators for simple geometries are openly available as part of some spectral element solvers. The preprocessor for FLEXI, HOPR, for instance, will generate cartesian boxes and meshes built from combinations of cartesian boxes, cylinders and spheres.
