- <b>Name</b> - allows to define the name of the hypothesis (MG-Tetra
Parameters by default).
+- <b>Algorithm Selection</b> - allows to select the version of MG-Tetra algorithm to be used.
+
- <b>Optimization level</b> - allows choosing the required
optimization level (higher level of optimization provides better mesh,
but can be time-consuming):
- medium (standard)
- - standard+
+ - standard+ (not available whem MG-Tetra HPC is selected)
- strong
- <b>Maximal size</b> - sets the maximum edge size in the generated mesh.
+- <b>Maximal number of threads</b> - define the maximal number of threads to be used by the meshing algorithm.
+ On selection of this box the Pthread mode is activated when MG-Tetra is selected and
+ Parallel mode is activated if the MG-Tetra HPC algorithm is selected.
+
+- <b>Pthread mode</b> - define the parallel strategy used by the mesher when MG-Tetra is selected.
+ - none
+ - aggresive - is faster than the sequential mode, but the quality of the resulting mesh may altered compared to the sequential mode.
+ - safe - is slower than the sequential mode, but the quality of the mesh can only improve;
+
+- <b>Paralle strategy (HPC)</b> - define the parallel strategy used by the mesher when MG-Tetra HPC is selected.
+ - none
+ - reproducible_given_max_number_of_threads
+ - reproducible
+ - aggressive
+
+
- <b>Volumic gradation</b> - Defines the volumic ratio between 2 consecutive elements.
WARNING: Changing the default value of this parameter may dramatically
decrease the quality of the resulting mesh.

+\subsection advanced_meshing_options Advanced meshing options for MG-Tetra algorithm
Advanced page tab expose mostly useful advanced options. Initially,
default values of the options are displayed and they are not
to a given maximum number of errors. At least 1 error is printed and
at most 100 errors are printed to prevent infinite loops.
-- <b>Maximal number of threads</b> - This allows to set the maximal
- number of threads the software can use in parallel for the
- multi-threading optimization mode.
-
- <b>No central point</b> - <b>yes</b> prevents adding an internal point at the
centre of gravity of the bounding box that MeshGems-Tetra uses by
default in order to speed up and to simplify the meshing
- <b>Optimise worst elements</b> - Applies an optimization processing
to improve the worst quality elements whenever possible.
-- <b>Mode of pthreads</b> - This option sets the optimization mode
- when using multithread capabilities. By default, this option is not
- activated which means that only a sequential optimization is
- performed.
-
- - <b>safe</b> is slower than the sequential mode, but the
- quality of the mesh can only improve;
-
- - <b>aggressive</b> - is faster than the sequential mode, but
- the quality of the resulting mesh may altered compared to the sequential mode.
-
- <b>Rectify jacobian</b> - This option activates correction of some
nodes so as to make the Jacobian of element strictly positive when
generating a quadratic mesh.
caracterizes a sliver : any tetrahedron which has at least an angle
below this value will be considered as a sliver.
+- <b>Target quality</b> - Sets the desired maximum target of worst
+ quality acceptable for the volume mesh used during optimisation
+ phase. When defined, an optimization processing is applied to
+ improve the quality until the given target is reached whenever
+ possible. By default, this option is not activated which means that
+ only the standard optimisations are performed (the quality target is
+ the target quality computed by the program).

+\subsection advanced_meshing_options_HPC Advanced meshing options for MG-Tetra and MG-Tetra HPC algorithms
+
+This option is common to both algorithms. When MG-Tetra HPC algorithm is selected on the General Parameters view, all advanced options
+are disabled except the follow ones:
+
- <b>Remove overconstrained tetrahedra</b> - This option can be used
to only split the tetrahadra which have at least two facets that
belong to the surface mesh. It will not split the overconstrained
- <b>only</b> means only correction is applied to an existing mesh.
-- <b>Target quality</b> - Sets the desired maximum target of worst
- quality acceptable for the volume mesh used during optimisation
- phase. When defined, an optimization processing is applied to
- improve the quality until the given target is reached whenever
- possible. By default, this option is not activated which means that
- only the standard optimisations are performed (the quality target is
- the target quality computed by the program).
