|
* This set of classes provides a thin wrapper around the exodusII
|
||
|
|
* internals. It supplants several of the exodusII API calls in
|
||
|
|
* order to avoid ncredef calls which totally rewrite the existing
|
||
|
|
* database and can be very expensive. These routines provide all
|
||
|
|
* required variable, dimension, and attribute definitions to the
|
||
|
|
* underlying netcdf file with only a single ncredef call.
|
||
|
|
*
|
||
|
|
* To use the application must create an Excn::Internals instance
|
||
|
|
* and call the Excn::Internals::write_meta_data() function. This
|
||
|
|
* function requires several classes as arguments including:
|
||
|
|
* <ul>
|
||
|
|
* <li> Mesh -- defines mesh global metadata
|
||
|
|
* <li> Block -- defines metadata for each block
|
||
|
|
* <li> NodeSet -- defines metadata for each nodeset
|
||
|
|
* <li> SideSet -- defines metadata for each sideset
|
||
|
|
* <li> CommunicationMetaData -- global metadata relating to
|
||
|
|
* parallel info.
|
||
|
|
* </ul>
|
||
|
|
*
|
||
|
|
* Calling Excn::Internals::write_meta_data(), replaces the
|
||
|
|
* following exodusII and nemesis API calls:
|
||
|
|
* <ul>
|
||
|
|
* <li> ex_put_init(),
|
||
|
|
* <li> ex_put_elem_block(),
|
||
|
|
* <li> ex_put_node_set_param(),
|
||
|
|
* <li> ex_put_side_set_param(),
|
||
|
|
* <li> ne_put_init_info(),
|
||
|
|
* <li> ne_put_loadbal_param(),
|
||
|
|
* <li> ne_put_cmap_params(),
|
||
|
|
* </ul>
