Straight-Edged Boxes

HOPR has several simple inbuilt mesh generators.

HOPR output: Mesh of multiple cartesian boxes with a stretched element arrangement

Cartesian Box

This tutorial shows how to generate a simple mesh of a cubical box and the definition of boundary conditions.

This is the parameter file, which is found in

tutorials/1-01-cartbox/parameter.ini

See Exemplary Variations for cases with different boundary conditions.

Periodic Boundary Conditions

This tutorial shows how to define periodic boundary conditions, only slightly changing the definitions from the tutorial Cartesian Box.

This is the parameter file, which is found in

tutorials/1-02-cartbox_periodic/parameter.ini

Multiple Cartesian Boxes

This tutorial shows how to generate a mesh consisting of mutliple cartesian boxes and how to link them via boundary conditions.

This is the parameter file, which is found in

tutorials/1-03-cartbox_multiple/parameter.ini

Stretching Functions

This tutorial shows how to generate a mesh consisting of a boxes with a stretched element arrangement.

This is the parameter file, which is found in

tutorials/1-04-cartbox_multiple_stretch/parameter.ini

Curved meshes

Curved Structured Mesh

This tutorial shows how to generate a curved structured mesh with an equidistant or with a stretched element arrangement alternatively.

This is the parameter file, which is found in

tutorials/1-05-curved_structured/parameter.ini


Mesh Curving by Post-Deformation

This tutorial shows how to generate a curved multi-block mesh, composed of several structured boxes, which are first assembled and then globally mapped to a curved domain

This is the parameter file, which is found in

tutorials/1-06-curved-postdeform/parameter.ini

Curved Torus

The same Post-Deformation applied to generate a torus

This is the parameter file, which is found in

tutorials/1-07-curved-torus/parameter.ini


Curved Sphere

The same Post-Deformation applied to generate a mesh of a sphere and a sphherical shell

This is the parameter file, which is found in

tutorials/1-08-curved-sphere/parameter.ini
