Adds a planar solid primitive with the specified vertices.  Planar solids offer a very convenient option to create custom, complex 3D geometries.  You can find more information about planar solids in this page: Structures - Planar solid.

 Supported Product: FDTD, MODE, DEVICE

 Syntax Description addplanarsolid; Adds an empty planar solid object. addplanarsolid(vtx, fct); Adds a planer solid object whose vertices are defined by 'vtx' and whose facets are defined by 'fct'

Example

The example below adds a planar solid cut-face box using two methods. The first method uses the facet table as a cell array and the second method uses the facet table a matrix.

method_type = 1;  # choose 1 or 2 to switch between methods

vtx = [0,0,0;

1,0,0;

1,1,0;

0,1,0;

0,0,2;

1,0,2;

1,1,2;

0,1,2]*1e-6;

# Method 1: facet table as cell array

a = cell(7);

for (i = 1:7) {

a{i} = cell(1);

}

a{1}{1} = [1,4,3,2];

a{2}{1} = [1,5,8,4];

a{3}{1} = [1,2,6,5];

a{4}{1} = [2,3,6];

a{5}{1} = [3,8,6];

a{6}{1} = [3,4,8];

a{7}{1} = [5,6,8];

if (method_type == 1) {

}

# Method 2: facet table as matrix

b = matrix(4,1,7); # max four points per polygon, max 1 polygon per facet

for (i = 1:7) {

fpoly = a{i}{1};

for (j = 1:length(fpoly)) {

b(j,1,i) = fpoly(j);

}

}

if (method_type == 2) {
