Hi,
After Installation of Salome 7.4.0, the following posts can be referred for starting to learn about drawing 2D rectangle (50*5) in salome and 3D box(l=200) in salome, and then performing the sample simulation. These posts have the corresponding solver input files and mesh files attached in them.
    1. Geometry Module
    i. New Entity>>Basic>>Vector
    Dx=100, Dy=100,Dz=100
    ii.New Entity>>Basic>>2D Sketch
    Values
    x=0,y=0 Apply
    x=50,y=0 Apply
    x=50,y=5 Apply
    x=0,y=5 Apply
    x=0,y=0 Apply and Close
    iii. New Entity>>Build>>Face (Objects = Sketch_n)
    iv. New Entity>>Explode (Face as main object, edge as subshapes)
    v. Rename by right clicking the edges at object browser for convenience

    2. Mesh Module
    i. Mesh>>Create Mesh (selection geometry = face, do necessary selections and apply + close)
    ii.Mesh >>Compute
    iii.Mesh >>Create Group
    -Mesh (=select mesh from object browser)
    -select edge
    -Group on geometry
    -Direct Geometry selection
    -select the previously exploded edges of face from object browser and apply+close.
    iv. Right click near Mesh at object browser and select export.
    v. Export>>unv

    1. Geometry Module
    i. New Entity>>Basic>>Vector
    Dx=10, Dy=10,Dz=10
    ii.New Entity>>Primitive>>Box
    Dimensions at origin
    Dx=200, Dy=200,Dz=200
    Apply and Close
    iii. New Entity>>Explode (Box_1 as main object, Face as subshapes)
    (If there are intersecting faces for complex 3D geometries, Operation>>Partition should be done at the faces and create >>geometry group should be done here at geometry module to provide sub-meshing option in Mesh module)
    v. Rename by right clicking the edges at object browser for convenience
    vi. Save the file as .hdf file

    2. Mesh Module
    i. Mesh>>Create Mesh (selection geometry = Box_1, do necessary selections and apply + close)
    (e.g. Tetrahedral meshing 3D, Tetrahedral Netgen in 2D-1D, Netgen 1-D)
    ii.Mesh >>Compute
    iii.Mesh >>Create Group
    -Mesh (=select mesh from object browser)
    -select face
    -Group on geometry
    -Direct Geometry selection
    -select the previously exploded faces of box from object browser and apply+close.
    iv. Right click near Mesh at object browser and select export
    v. Export file in .unv format

Notes
1. Amidst the posts in the above links, there are provided the brief description for steps of drawing geometry and mesh in Salome 7.4.0 compatible for export to Elmer.
2. Some Basic Commands in Elmer (Salome to Elmer)
    i. Conversion of .unv file to ElmerSolver format
    Code: Select all
    $ElmerGrid 8 2 meshfilename.unv -autoclean

    ii. Elmer Solver run command
    Code: Select all
    $ElmerSolver filename.sif

    or
    Code: Select all
    $ElmerSolver > filenameforsolverlog.log 2>&1
    (if filename.sif is provided in the ELMERSOLVER_STARTINFO file)

Exporting Mesh from Salome to Other Softwares

A. Salome to Elmer
1. Export Salome Mesh in .unv format (output file = Mesh_1.unv )
2. Jump into the directory containing Mesh_1.unv and type
Code: Select all
$ElmerGrid 8 2 Mesh_1.unv -autoclean


B. Salome to OpenFOAM
Method I (In OpenFOAM)
1. Export Salome Mesh in .unv format (output file = Mesh_1.unv )
2. Put the Mesh_1.unv outside the system folder containing controlDict file. controlDict file is a file required by a test in OpenFOAM.
3. Jump into the directory containing Mesh_1.unv file and type the following openFOAM command.
Code: Select all
$ideasUnvToFoam Mesh_1.unv


Method II(Within Salome)
1. Download salomeToOpenFOAM.py from https://github.com/nicolasedh/salomeToOpenFOAM
2.In Salome, save the project (Geometry, Mesh) as Study1.hdf
3.In Salome, at Mesh module select the particular mesh and go to: File >>Load Script>> salomeToOpenFOAM.py
4. This script will convert your mesh to NameOfMesh/constant/polyMesh.

Hi,
Importing Salome Mesh in .unv format in MOOSE software (exporting .unv from salome and importing by libmesh in MOOSE framework)
http://www.salome-platform.org/
http://mooseframework.com/
http://mooseframework.org/wiki/MooseSystems/Mesh/
https://github.com/idaholab/moose/blob/ ... als/ex08.i

Steps
A. Create Mesh Groups in Salome Mesh Module
Let's consider a cube , so we have :
i. In Mesh Module, after the computation of mesh, apply
Code: Select all
Create Groups

ii. Define the names for each faces i.e. the members of resulting Mesh Groups(for boundaries) as:
Code: Select all
Left , Right, Top, Bottom, Front and Back.

iii. Export the Mesh in .unv format i.e. in object browser,
Right Click the Mesh-->> Export -->> .unv
iv. Save the file as "filename.unv"

B. Open the filename.unv, and visit universal dataset number 2467, which are named as Permanent Groups and in simple, mean the Mesh Groups that has been created above.
The group having the above Left , Right, Top, Bottom, Front and Back can be found there.

C. In the input file of MOOSE software say "moosefile.i" , define the following things in the Mesh section.
Code: Select all
[Mesh]
    file=filename.unv
    boundary_id='1 2 3 4 5 6'
    boundary_name='Left Right Top Bottom Front Back'
[]

This means the boundary name "Left" of filename.unv file has got an identity number 1 for use in MOOSE framework and so on.

D. Now, in the same moosefile.i, we define the following in the BCs section
Code: Select all
[BCs]
  active = 'first second'

  [./first]
    type = DirichletBC
    variable = varname
    boundary = '1'
    value = 5
  [../]

  [./second]
    type = DirichletBC
    variable = varname
    boundary = '2'
    value = 0
  [../]
[]

In these BCs, boundary='1' and boundary='2' respectively refer to Left and Right boundary names of the cube in filename.unv.

The steps for installation of MOOSE software in Ubuntu 14.04 at the home directory along with a hint on running an application is given in this thread.

In context of multibodies the corresponding task is done for blocks name in MOOSE input file in addition to the boundaries names:
Code: Select all
[Mesh]
file = MeshFile.unv
block_id = '1 2'
block_name = 'material_1 material_2'
#material_1 and material_2 are found in MeshFile.unv
# if they are defined by Mesh create groups option
boundary_id = '1 2 3 4'
boundary_name = 'left right top bottom'
#left right top bottom are found written in the MeshFile.unv
## if they are defined by Mesh create groups option
[ ]

and these material names are represented as names in the Materials block such as:
Code: Select all
[Materials]
...
[./FirstMaterials]
...
block = 'material_1'
...
[ ../]
[./SecondMaterials]
...
block = 'material_2'
...
[ ../]

Reading the names of Target Boundaries and Bodies of Salome Mesh by Elmer Solver:
The following link can be referred to :-
http://www.elmerfem.org/forum/viewtopic ... 175c335e3c

where, it is expressed that
raback wrote:When working with Salome there is a way to maintain names when exporting in UNV format for Elmer. In Elmer analysis can then directly use these names, for example, as
Code: Select all
    Simulation
      ...
      Use Mesh Names = True
    End

    Body 1
      Name = mixer
      ...
    End
    ...
    Boundary Condition 7
      Name = inlet
      Velocity 1 = 1.0
    End
