This class defines an abstract interface for Mesh
output.
Specific classes derived from this class actually implement writing various mesh formats.

Default constructor.
Will set the _obj to nullptr, effectively rendering this object useless.
Definition at line 194 of file mesh_output.h.
|
explicitprotected |
Constructor.
Takes a reference to a constant object. This constructor will only allow us to write the object.

unsigned int & libMesh::MeshOutput< MT >::ascii_precision | ( | ) |
Return/set the precision to use when writing ASCII files.
By default we use numeric_limits<Real>::digits10 + 2, which should be enough to write out to ASCII and get the exact same Real back when reading in.

This method should be overridden by "parallel" output formats for writing nodal data.
Instead of getting a localized copy of the nodal solution vector, it is passed a NumericVector of type=PARALLEL which is in node-major order i.e. (u0,v0,w0, u1,v1,w1, u2,v2,w2, u3,v3,w3, ...) and contains n_nodes*n_vars total entries. Then, it is up to the individual I/O class to extract the required solution values from this vector and write them in parallel.
If not implemented, localizes the parallel vector into a std::vector and calls the other version of this function.
Reimplemented in libMesh::Nemesis_IO.

Flag specifying whether this format is parallel-capable.
If this is false (default) I/O is only permitted when the mesh has been serialized.
Definition at line 159 of file mesh_output.h.
|
private |
A pointer to a constant object.
This allows us to write the object to file.
Definition at line 177 of file mesh_output.h.
|
protected |
Flag specifying whether this format can be written by only serializing the mesh to processor zero.
If this is false (default) the mesh will be serialized to all processors
