New() [1/6]

MEDFileCMesh * MEDFileCMesh::New ( )

static

Returns an empty instance of MEDFileCMesh.

Returns

MEDFileCMesh * - a new instance of MEDFileCMesh. The caller is to delete this mesh using decrRef() as it is no more needed.

Referenced by New(), MEDCoupling::MEDFileMesh::New(), and MEDCoupling::WriteMesh().

New() [2/6]

MEDFileCMesh * MEDFileCMesh::New ( const std::string &  fileName, MEDFileMeshReadSelector *  mrs = 0  )

static

Returns a new MEDFileCMesh holding the mesh data that has been read from a given MED file. The first mesh in the file is loaded.

Parameters

[in]

fileName

- the name of MED file to read.

Returns

MEDFileCMesh * - a new instance of MEDFileCMesh. The caller is to delete this mesh using decrRef() as it is no more needed.

Exceptions

If	the file is not readable.
If	there is no meshes in the file.
If	the mesh in the file is not a Cartesian one.

MEDFileCMesh * MEDFileCMesh::New ( const std::string &  fileName, const std::string &  mName, int  dt = -1, int  it = -1, MEDFileMeshReadSelector *  mrs = 0  )

static

Returns a new MEDFileCMesh holding the mesh data that has been read from a given MED file. The mesh to load is specified by its name and numbers of a time step and an iteration.

Parameters

[in]	fileName	- the name of MED file to read.
[in]	mName	- the name of the mesh to read.
[in]	dt	- the number of a time step.
[in]	it	- the number of an iteration.

Returns

MEDFileCMesh * - a new instance of MEDFileCMesh. The caller is to delete this mesh using decrRef() as it is no more needed.

Exceptions

If	the file is not readable.
If	there is no mesh with given attributes in the file.
If	the mesh in the file is not a Cartesian one.
