Description

The FHPlane tool inserts a FastHenry uniform conductive plane object.

FastHenry FHPlane

Usage

The FHPlane object must be based on another object, that can be either a Draft Rectangle or a Part Box object. In case you based your FHPlane on a Part Box object, the Thickness parameter will be inherited from the Box Height value.

  1. Create and select a Draft Rectangle or a Part Box object
  2. Press the EM FHPlane button, or press E then P keys.

In addition, you can also select together with the base object (the Draft Rectangle or the Part Box) also one or more EM FHNode and / or one or more EM FHPlaneHole objects, that will be adopted by the FHPlane:

  1. Create a Draft Rectangle or a Part Box object
  2. Create one or more EM FHNode objects
  3. Create one or more EM FHPlaneHole objects
  4. Select the base object, the FHNode objects and the FHPlaneHole objects (for this multiple selection, you can point and click the objects in the tree view or in the 3D view, and to perform a multiple selection just keep the CTRL key pressed while selecting).
  5. Press the EM FHPlane button, or press E then P keys.

Remarks:

A FastHenry uniform conductive plane object is formed by laying down a gird of nodes (hereafter called 'internal nodes') and connecting the nodes with a 2D mesh of segments in the (relative) X and Y directions. Holes are formed in the plane by removing some internal nodes, and hence also the segments that connects to those nodes. For more details on FastHenry uniform conductive planes, you should review the FastHenry user's guide.

Properties

Scripting

See also: FreeCAD Scripting Basics.

The FHPlane object can be used in macros and from the Python console by using the following function: 

plane = makeFHPlane(baseobj=None, thickness=None, seg1=None, seg2=None, nodes=[], holes=[], name='FHPlane')

Example: 

import FreeCAD, Draft, EM

pl = FreeCAD.Placement()
pl.Rotation.Q = (0.0,0.0,0.0,1.0)
pl.Base = FreeCAD.Vector(1.0,1.0,0.0)
rec = Draft.makeRectangle(length=10.0,height=5.0,placement=pl,face=True,support=None)

fhnode1 = EM.makeFHNode(X=1.0,Y=3.5,Z=0)
fhnode2 = EM.makeFHNode(X=8.0,Y=3.5,Z=0)

hole = EM.makeFHPlaneHole(X=6.0,Y=3.5,Z=0.0)

fhplane = EM.makeFHPlane(rect, thickness=1.0, seg1=15, seg2=15, nodes=[fhnode1, fhnode2], holes=[hole])
