Data For Triangles
Data for triangles consist of metallic triangles, edges, symmetry, dielectric triangles as well as advanced information for corner and end points.
Metallic Triangles
For the metallic triangles the following extract is written:

The first column gives the number of the triangle. The second column gives the label followed by the medium in which the triangle is situated. A 0 means that the triangle is in free space. The next three columns are the X coordinate, Y coordinate and Z coordinate of the three corner points of the triangles.
In the first row of each triangle follows another list of the numbers of the edges of the adjacent triangles. A positive sign indicates that the positive current direction is away from the triangle. A negative sign indicates that the positive current direction is towards the triangle. The area of the triangle is given below the edges in m2.
Metallic Triangle Edges
The data for the metallic triangle edges is given after the metallic triangles. Such an edge is generated wherever two triangles have two common vertices. An additional line (or row) gives the components (nx, ny, nz) of the normal vector of each triangle.

The next four columns contain information regarding the symmetry. The column yz gives the number of the edge corresponding to the X=0 plane (YZ plane) of symmetry. A positive sign indicates that the currents are symmetric and a negative sign indicates that the currents are anti-symmetric. If there is a 0 present in this column then a symmetric edge does not exist. The same applies to the next columns xz and xy concerning the Y=0 plane and the Z=0 plane.
If the last column with the heading status displays unknown then the edge has an unknown status. This means that the applicable coefficient of the current basis function cannot be determined from the symmetry, but has to be determined form the solution of the matrix equation. If a 0 is displayed instead then the coefficient of the current basis function is 0 due to electric or magnetic symmetry and does not have to be determined.
If there is any other number in the status column then this number indicates another edge for which the coefficient is equal to (positive sign in the status column) or the negative of (negative sign in the status column) the coefficient of the current basis function. From symmetry the coefficient of the current triangle does not have to be determined.
