Octave / FEM / fc_vfemp1/ Installation

One just has to get/download the install ﬁle ofc_vfemp1_install.m Thereafter, one run it under Octave. This command download, extract and conﬁgure the pict package and all the required packages in the current directory.

For example, to install this package in ~/Octave directory, one has to copy the ﬁle mfc_vfemp1_install.m in the ~/Octave directory. Then in a Octave terminal run the following commands

Octave Console

>> cd ~/Octave
>> mfc_vfemp1_install

There is the output of the mfc_vfemp1_install command on a Linux computer :

2- Setting the <fc-vfemp1> package
Write in ~/Octave/fc-vfemp1-full/fc_vfemp1-0.2.0/configure_loc.m ...
3- Using packages :
   ->             fc-tools : 0.0.31
   ->             fc-bench : 0.1.2
   ->         fc-hypermesh : 1.0.3
   ->              fc-amat : 0.1.1
   ->         fc-meshtools : 0.1.3
   ->     fc-graphics4mesh : 0.1.2
   ->            fc-oogmsh : 0.2.3
   ->             fc-siplt : 0.2.1
   ->            fc-simesh : 0.4.1
with            fc-vfemp1 : 0.2.0
*** Using instructions
   To use the <fc-vfemp1> package:
   addpath(’~/Octave/fc-vfemp1-full/fc_vfemp1-0.2.0’)
   fc_vfemp1.init()

   See ~/Octave/ofc_vfemp1_set.m

The complete package (i.e. with all the other needed packages) is stored in the directory ~/Octave/fc-vfemp1-full and, for each Octave session, one have to set the package by :

Octave Console

>> addpath(’~/Octave/fc-vfemp1-full/fc-vfemp1-0.2.0’)
>> fc_vfemp1.init()

If it’s the ﬁrst time the fc_vfemp1.init() function is used, then its output is

Otherwise, the output of the fc_vfemp1.init() function is

To quickly test this toolbox, one can run one of the script examples located in the directory +fc_vfemp1/+examples. For example, runs

Octave Console

>> fc_vfemp1.examples.BVPCondenser2D01

or the complete demo (take a long time)

Octave Console

>> fc_vfemp1.demos()

To install the fc-vfemp1 package without graphical extension one can use the following command

Octave Console

>> ofc_vfemp1_install(’graphics’,false)

For uninstalling, one just have to delete directory

~/Octave/fc-vfemp1-full
