is an Octave package which allows to mesh any d-orthotope (hyperrectangle in dimension d) and their m-faces with simplices or orthotopes. The versions prior to 1.0.0 were created to show the implementation of the algorithms given in the report

Vectorized algorithms for regular tessellations of d-orthotopes and their faces .

From version 1.0.0, tesselation with p-order simplices or p-order orthotopes is provided and associated vectorized algorithms are described in the report:

Vectorized algorithms for regular tessellations of d-orthotopes and their faces with high-order orthotopes or simplicial elements .

This package uses Octave objects and is provided with meshes visualisation tools for dimension less than or equal to 3.

  Snapshots

This package was only tested on Ubuntu 22.04.1 with Octave 7.3.0.

Here are two methods of installations. The first uses the Octave pkg command and the second a provided Octave script.

  All-in-one installation

For this method, one just has to get/download the install file ofc_hypermesh_install.m Thereafter, it should be run under Octave. This command downloads, extracts and configures the fc-hypermesh and all the required packages in the current directory.

For example, to install this package in directory ~/Octave/packages, in a terminal one can do:

# mkdir -p ~/Octave/packages 
# cd ~/Octave/packages 
# wget https://www.math.univ-paris13.fr/~cuvelier/software/codes/Octave/fc-hypermesh/1.0.4/ofc_hypermesh_install.m

Then in a Octave terminal run the following commands

>> cd ~/Octave/packages 
>> ofc_hypermesh_install

This is the output of the ofc_hypermesh_install command:

1- Downloading and extracting the packages 
2- Setting the <fc-hypermesh> package 
Write in ~/Octave/packages/fc-hypermesh-full/fc_hypermesh-1.0.4/configure_loc.m ... 
3- Using packages : 
   ->             fc-tools : 0.0.35 
   ->             fc-bench : 0.1.3 
*** Using instructions 
   To use the <fc-hypermesh> package: 
   addpath(’~/Octave/packages/fc-hypermesh-full/fc_hypermesh-1.0.4’) 
   fc_hypermesh.init() 
 
   See ~/Octave/packages/ofc_hypermesh_set.m

The complete package (i.e. with all the other needed packages) is stored in the directory

and, for each Octave session, one has to set the package by:

>> addpath(’~/Octave/packages/fc-hypermesh-full/ofc-hypermesh-1.0.4’) 
>> fc_hypermesh.init()

To uninstall, one just has to delete directory

  Installation via pkg command

• Download the packages. For example, in a terminal:

  Linux Console

  wget https://www.math.univ-paris13.fr/~cuvelier/software/codes/Octave/fc-tools/0.0.34/fc-tools-0.0.35.tar.gz 
  wget https://www.math.univ-paris13.fr/~cuvelier/software/codes/Octave/fc-bench/0.1.3/fc-bench-0.1.3.tar.gz 
  wget https://www.math.univ-paris13.fr/~cuvelier/software/codes/Octave/fc-hypermesh/1.0.4/fc-hypermesh-1.0.4.tar.gz

• Under Octave :

  Octave Console

  >> pkg install fc-tools-0.0.35.tar.gz 
  >> pkg install fc-bench-0.1.3.tar.gz 
  >> pkg install fc-hypermesh-1.0.4.tar.gz

  With all Octave releases beginning with 4.4.0, one can directly use

  Octave Console

  >> pkg install https://www.math.univ-paris13.fr/~cuvelier/software/codes/Octave/fc-tools/0.0.35/fc-tools-0.0.35.tar.gz 
  >> pkg install https://www.math.univ-paris13.fr/~cuvelier/software/codes/Octave/fc-bench/0.1.3/fc-bench-0.1.3.tar.gz 
  >> pkg install https://www.math.univ-paris13.fr/~cuvelier/software/codes/Octave/fc-hypermesh/1.0.4/fc-hypermesh-1.0.4.tar.gz

• Now to use fc-hypermesh in any Octave session, it is necessary to load and initialize the package :

  Octave Console

  >> pkg load fc-hypermesh 
  >> fc_hypermesh.init()

• To try the package, one can launch a demo:

  Octave Console

  >> fc_hypermesh.demos.demo01

For uninstalling the package, just do in an Octave session:

>> pkg uninstall fc-hypermesh 
>> pkg uninstall fc-bench 
>> pkg uninstall fc-tools
