Evolutions of the module

Here are the main evolutions de HOMARD from the first release in SALOME 6.5.

  • Interface with med 3.0.6
  • Default values for the time steps
  • New element types: TRIA7 and QUAD9
  • Optional output into the MED file of the level of refinement of every element
  • Correction of a bug in the filtering of the refinement by groups
  • Driving of the adaptation by a threshold that is based upon the mean and the standard deviation (see The hypothesis)
  • TUI: the last time step for the driving instant can be selected by SetTimeStepRankLast (see The iteration)
  • The destruction of the objects is available (GUI and TUI)
  • The TUI functions are modified: they act onto the objects and no more by the names: homard.AssociateIterHypo(iter_name,hypo_name) becomes iter.AssociateHypo(hypo_name), homard.AssociateHypoZone(hypo_name,zone_name,type_use) becomes hypo.AddZone(zone_name,type_use), homard.CreateIteration(iter_name,iter_parent_name) becomes case.NextIteration(iter_name) or iter.NextIteration(iter_name)
  • Addition of a function: cas.LastIteration() : returns the last iteration of the case (see The iteration)
  • Mesh analysis (see Mesh analysis)
  • A cone can be used as a support for a 2D boundary (see The boundary)
  • The result can be published or not published in SMESH (see The iteration) iter.Compute(option) becomes iter.Compute(option1, option2)
  • A serie of iterations that is stored in a directory can be followed (see The creation of a case)
  • English documentation
  • Options to track the computation (see The iteration): iter.SetInfoCompute(MessInfo)
  • Automatic creation of YACS schema: case.WriteYACSSchema(ScriptFile, DirName, MeshFile): writes a schema YACS relative to the case (see The case)
  • The initial mesh is not published in SMESH.
  • The refinement of 2D meshes with quadrangles is improved to take into account ‘staircases’.
  • The fields overs elements can be interpolated with two ways: intensive or extensive.
  • The time steps for the interpolation of the files can be choosen: SetFieldInterpTimeStep(FieldInterp, TimeStep): defines the time step for the interpolation of the field (see The iteration) SetFieldInterpTimeStepRank(FieldInterp, TimeStep, Rank): defines the time step and the rank for the interpolation of the field (see The iteration)
  • If error occurs into the python instructions, the program stops.
  • Scroll bar for the large windows.
  • The meshes are published only if requested.
  • The torus is a new possibility for the analytical boundary.
  • The function SetAdapRefinUnRef(TypeAdap, TypeRaff, TypeDera) is suppressed. For an adaptation by a field or by zones, the mode refinement/unrefinement is automatically set from the other parameters of the hypothesis. For a uniform refinement, the function SetUnifRefinUnRef(TypeRaffDera) is now used (see The hypothesis).
  • If an error occurs, the name of the message file is displayed.
  • Release 11.1 for the HOMARD binary. The conformal refinement of the meshes with hexaedra is improved: less meshes are produced.
  • Additional extra output: diameters and qualities; the function SetExtraOutput(option) is now used (see The hypothesis).
  • Release 11.2 for the HOMARD binary ; improvement for the 1D curve boundaries.
  • Interpolation of all the fields into the input file.
  • Interface with med 3.2.0
  • New options within the choice conformal/non-conformal.
  • Less meshes are involved in the case of a non conformal refinement of a mesh made of hexahedra.
  • Correction of an error when refinement and unrefinement are coupled for a mesh made of hexahedra.
  • Interface with med 3.2.1
  • Output of the list of the meshes that are connected with a non conformal link.
  • Interface with med 3.3.0
  • Correction for the conformal coarsening of a set of hexaedra
  • Correction of the interpolation od a volumic field over prisms which are splitted into tetrahedra and pyramids
  • Integer MED fields to glue the elements with different levels when non conformal refinement is used
