Matlab / Mesh / fc_simesh/ Installation

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

For example, to install this toolbox in ~/Matlab directory, one has to copy the ﬁle mfc_simesh_install.m in the ~/Matlab directory. Then in a Matlab terminal run the following commands

Matlab Console

>> cd ~/Matlab
>> mfc_simesh_install

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

1- Downloading and extracting the toolboxes
2- Setting the <fc-simesh> toolbox
Write in ~/Matlab/fc-simesh-full/fc_simesh-0.4.2/configure_loc.m ...
3- Using toolboxes :
   ->             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> toolbox:
   addpath(’~/Matlab/fc-simesh-full/fc_simesh-0.4.2’)
   fc_simesh.init()

   See ~/Matlab/mfc_simesh_set.m

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

Matlab Console

>> addpath(’~/Matlab/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

Matlab Ouput

fc_oogmsh[0.2.3], fc_siplt[0.2.2].

For uninstalling, one just have to delete directory

~/Matlab/fc-simesh-full

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

Matlab Console

>> fc_simesh.demos.feval2D01()

Matlab Console

>> fc_simesh.demos.plot2D()

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

Matlab Console

>> fc_simesh.demos.alldemos()

To use another gmsh binary, one can use the fc_oogmsh.configure Matlab function as

Matlab Console

>> fc_oogmsh.configure(’gmsh_bin’,’<PATH TO>/gmsh’)

where <PATH TO> will be replaced by the path to the gmsh binary. See

for more details.
