Installation automatic, all in one (recommanded)

For this method, one just have to get/download the install ﬁle (5 Ko) ofc_simesh_install.m Thereafter, one run it under Octave. This command download, extract and conﬁgure the fc-simesh and the required packages (fc-tools, fc-oogmsh, fc-hypermesh) in the current directory.

For example, to install this package in ~/Octave/packages directory, one have to copy the ﬁle ofc_simesh_install.m in the ~/Octave/packages directory. Then in a Octave terminal run the following commands to install the fc-simesh package with graphical extension

Octave Console

>> cd ~/Octave/packages
>> ofc_simesh_install

There is the output of the ofc_simesh_install command on a Linux computer :

3- Using instructions
   To use the <fc-simesh> package:
   addpath(’~/Octave/packages/./fc-simesh-full/fc_simesh-0.2.1’)
   fc_simesh.init()

   See ~/Octave/packages/ofc_simesh_set.m

The complete package (i.e. with all the other needed packages) is stored in the directory ~/Octave/packages/fc-simesh-full and, for each Octave session, one have to set the package by :

Octave Console

>> addpath(’~/Octave/packages/fc-simesh-full/fc-simesh-0.2.1’)
>> fc_simesh.init()

To install the fc-simesh package without graphical extension one can use the following command

Octave Console

>> ofc_simesh_install(’graphics’,false)

For uninstalling, one just have to delete directory

~/Octave/packages/fc-simesh-full

To quickly test this package, one can run one of the examples located in the directory fc_simesh-0.2.1/+fc_simesh/+demos. For example, runs

Octave Console

>> fc_simesh.demos.feval2D01()

or the complete demo (take a long time)

Octave Console

>> fc_simesh.demos.alldemos()
