MPhys DVGeo Component

class pygeo.mphys.mphys_dvgeo.OM_DVGEOCOMP(*args, **kwargs)[source]

Set up a geometry component with either 1 DVGeo or multiple DVGeos.

A single DVGeo are initialized by specifying its file and type and, optionally, additional options. Available options can be found in the specific DVGeometry class.

Multiple DVGeos are initialized in a dictionary of these values and must have a unique name. The format is:

>>> DVGeoInfo = {
>>>     "name1": {"file": file1, "type": type1, "options": options1}
>>>     "name2": {"file": file2, "type": type2, "options": options2}
>>> }

The two setup methods cannot currently be used together.

nom_addComponent(comp, ffd_file, triMesh, DVGeoName=None)[source]

Add a component a DVGeometryMulti object. This is a wrapper for the DVGeoMulti.addComponent method.

Parameters:

compstr: The name of the component.
ffd_filestr: Path to the FFD file for the new DVGeo object for this component.
triMeshstr, optional: Path to the triangulated mesh file for this component.
DVGeoNamestr, optional: The name of the DVGeo object to add this component to.

nom_addGlobalDV(dvName, value, func, childName=None, comp=None, isComposite=False, DVGeoName=None, prependName=False, config=None)[source]

Raises:

RuntimeError: Raised if the underlying DVGeo object is not an FFD
