BurgerFilter

class BurgerFilter

Allows to change the convention of the computed displcement discontinuity (also known as Burger vectors). By default, the convention is as described by Okada. It is possible to use another convention such as the one defined in Poly3D by mean of this class.

setAxisOrder(order: [str, str, str])

The order of the axis. An array of 3 strings which can be either dip, strike or normal. Typically, this property is used to order the components of the displacement when calling Surface.displ, Surface.displPlus or Surface.displMinus (or equivalently Solution.burgers, Solution.burgersPlus or Solution.burgersMinus).

setAxisRevert(revert: [bool, bool, bool])

Revert of the displacement vectors axis.

apply(burgers: Vectord) → Vector

Apply the filter to a given burger list (provided as a flat array)

setupOkada()

Convenient method to switch to Okada convention (default one). It corresponds to

axisOrder  = ['normal', 'strike', 'dip']
axisRevert = [False   , False   , False]

setupPoly3D()

Convenient method to switch to Poly3D convention. It corresponds to

axisOrder  = ['dip', 'strike', 'normal']
axisRevert = [True , False   , False   ]

Usage

const filter = BurgerFilter()
filter.setAxisOrder (["dip", "strike", "normal"])
filter.setAxisRevert([ True,  False  ,  False  ])
burgers = filter.apply( surface.displ() )
