               Genesis

Model of Genesis/ExodusII file, based on netCDF reader wrapper. The Genesis/ExodusII file must meet the following criteria: (i) have at least one block, (ii) each block needs a name, and (iii) each sideset (BC) needs a name.

Method Details

init(self, *arg, **kw)
(Constructor)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:

path - the file to open.
omode - opening mode.

Overrides: object.__init__

(inherited documentation)

get_attr_text(self, name, varname)

Get the attribute text attached to an variable.

Parameters:

name (str) - name of the attribute.
varname (str) - name of the variable.

Returns: str

the text.

load(self)

Load mesh data.

Returns:: nothing

toblock(self, onlybcnames=None, bcname_mapper=None, fpdtype=None)

Convert Cubit/Genesis/ExodusII object to Block object.

Parameters:

onlybcnames (list) - positively list wanted names of BCs.
bcname_mapper (dict) - map name to bc type number.
fpdtype (str) - floating-point dtype.

Returns: solvcon.block.Block

Block object.

_convert_interior_to(self, blk)

Convert interior connectivities to Block object.

Parameters:

blk (solvcon.block.Block) - to-be-written Block object.

Returns:

nothing

_convert_bc_to(self, blk, onlynames=None, name_mapper=None)

Convert boundary condition information into Block object.

Parameters:

blk (solvcon.block.Block) - to-be-written Block object.
onlynames (list) - positively list wanted names of BCs.
name_mapper (dict) - map name to bc type and value dictionary; the two objects are organized in a tuple.

Returns:

nothing.

_tobc(self, ibc, blk)

Extract boundary condition information from self to become a BC object. Only process element/cell type of boundary information.

Parameters:

ibc (int) - index of the BC to be extracted.
blk (solvcon.block.Block) - Block object for reference, nothing will be altered.

Returns: solvcon.boundcond.BC

generic BC object.
