SetMaterialWeight

SetMaterialWeight(CSX, name, varargin)

Full definition:

function CSX = SetMaterialWeight(CSX, name, varargin)

Define the material weighting function(s)

The functions can use the variables:

• x,y,z

• rho for the distance to z-axis

• r for the distance to origin

• a for alpha (as in cylindircal and spherical coord systems)

• t for theta (as in the spherical coord system

  all these variables are not weighted with the drawing unit defined by the grid

example:

%material distribution as a rect-function with 4 periods
start=[-500 -100 -500];
stop =[ 500  100  500];
CSX = AddMaterial(CSX, 'material');
CSX = SetMaterialProperty(CSX, 'material', 'Epsilon', 1);
CSX = SetMaterialWeight(CSX, 'material', 'Epsilon', ['(sin(4*z / 1000 *2*pi)>0)+1']);
CSX = AddBox(CSX, 'material' ,10 , start, stop);
