3.2 Options

All options are given in command line:

$\bullet$

-O $n$ with $n$ an integer:

-O 0	:	mesh optimization.
-O 1	:	mesh generation in agreement with a prescribed metric,
		including points insertion/suppression and mesh optimization.
-O 4	:	option 1 + global splitting,
		warning global splitting involves splitting of boundaries (triangles)
-O 9	:	rigid bodies displacement and optimization (see 5).
-O 10	:	transformation of an hexahedral/prism mesh into tetrahedral one (see 6).
-O-1	:	same as described previously without the optimization phase.

$\bullet$

-d : debug mode.

$\bullet$

-h : command summary, the following message will be written in your xterm:

  -- MMG3d, Release 4.0 c (March 6, 2012) 
     Copyright (c) LJLL/IMB, 2010
usage: mmg3d4.0 [-v[n]] [-h] [-m n] [opts..] filein[.mesh] [-out fileout]

** Generic options :
-d      Turn on debug mode
-h      Print this message
-v [n]  Tune level of verbosity
-m [n]  Set memory size to n Mbytes

-O [n]  Optimization level
  1      adaptation
  4      use global splitting (warning modify boundary mesh)
  9      moving mesh
  10     transform an hexahedral/prism mesh in a tetrahedral mesh 
 -n      turn off optimisation

** Misc. options
-bucket [n]    Specify the size of bucket per dimension
-noswap        no edge or face flipping
-nomove        no point relocation
-noinsert      no new point
-out fileout   Specify output file name
-rn n num      Specify the number of vertices by box to renumber nodes and the renumberings
-dt dt         to compute the node speed

$\bullet$

-v $n$
$n$ defines the verbosity level (defaulft $3$).

$\bullet$

-m $n$
the integer $n$ defines the allocated memory in Megabytes.
By default, the software allows to generate a mesh with maximum $500 000$ points or $3 000 000$ tetrahedra.

$\bullet$

-mov name : gives the displacement filename (option 9, see 5).

$\bullet$

-dt t : to compute the node speed (option 9, see 5).

$\bullet$

-in name : gives the input filename.

$\bullet$

-out nom : gives the output filename.

$\bullet$

-bucket : specifies the bucket size (default $64$).

$\bullet$

-noswap : generates the mesh without applied edge swaps.

$\bullet$

-noinsert : generates the mesh in keeping constant the number of nodes (no points insertion or edge deletion).

$\bullet$

-nomove : generates the mesh without point relocation in optization stage.

$\bullet$

-rn $n$ $num$ : this option concerns renumbering stage. The integer $n$ is the number of vertices by box (by default $500$) and $num$ allows to tell when the renumbering stage appears: $0$: no renumbering stage ; $1$: renumbering at beginning ; $2$: renumbering after insertion stage ; $3$ (default): renumbering at the beginning and after insertion stage.
