Octave / Mesh / fc_simesh/ Installation

One just has to get/download the install ﬁle ofc_simesh_install.m Thereafter, one run it under Octave. This command download, extract and conﬁgure the pict packages and all the required packages in the current directory.

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

Octave Console

>> cd ~/Octave
>> ofc_simesh_install

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

1- Downloading and extracting the packages
2- Setting the <fc-simesh> package
Write in ~/Octave/fc-simesh-full/fc_simesh-0.4.2/configure_loc.m ...
3- Using packages :
   ->             fc-tools : 0.0.31
   ->             fc-bench : 0.1.2
   ->         fc-hypermesh : 1.0.3
   ->              fc-amat : 0.1.2
   ->         fc-meshtools : 0.1.3
   ->     fc-graphics4mesh : 0.1.3
   ->            fc-oogmsh : 0.2.3
   ->             fc-siplt : 0.2.2
with            fc-simesh : 0.4.2
*** Using instructions
   To use the <fc-simesh> package:
   addpath(’~/Octave/fc-simesh-full/fc_simesh-0.4.2’)
   fc_simesh.init()

   See ~/Octave/ofc_simesh_set.m

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

Octave Console

>> addpath(’~/Octave/fc-simesh-full/fc-simesh-0.4.2’)
>> fc_simesh.init()

If it’s the ﬁrst time the fc_simesh.init() function is used, then its output is

fc_oogmsh[0.2.3], fc_siplt[0.2.2].

Otherwise, the output of the fc_simesh.init() function is

fc_oogmsh[0.2.3], fc_siplt[0.2.2].

For uninstalling, one just have to delete directory

~/Octave/fc-simesh-full

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

Octave Console

>> fc_simesh.demos.feval2D01()

Octave Console

>> fc_simesh.demos.plot2D()

or the complete demo (without graphics, testing various MSH ﬁle format, take a long time)

Octave Console

>> fc_simesh.demos.alldemos()
