Geometries Design

中文/English

The figures show below are output file : the file name; the variable matrix : the variable in Matlab GUI; and the default value.

if we set the total grid size:

X=120;

Y=130;

Z=140;

then size(geox)=120,130,140

The following are the methods that can create the geometries for FonSinEM

Example : a metallic sphere

【Input panel】use the built-in geometries function : Iso_Sphere

%=================球 sphere===========================

radius=150e-9;  %diameter=2*radius

nindex=1^2;

sigma=0;

choice='E_Model1'; %E_Iso,PEC,M_Iso,PMC,E_Model1,M_Model1,EM_Model1

gridtype=-1; %electric material -1; magnetic material 1; other 0

xposition=icenter*gdx;

yposition=jcenter*gdy;

zposition=kcenter*gdz;

Iso_Sphere(choice,gridtype,nindex,sigma,xposition,yposition,zposition,radius)

%=================球 sphere===========================

The FonSinEM built-in function text file is 『FonSinEM_Geometries.txt』.

Also you can open this file at 【指令變數(Command Variables)=>結構(Geometries)】

To create a geometries step

1. checked the 【☑結構設計(Design Structures)】 and checked the materials if will be used

2. push the 【☑建立 (create)】 button

two methods

3a. method 1 : input the geometries function in 【input panel】

3b. method 2 :import 2D figure or 3D CAD (*.STL) file

4.plot the geometries and check it if correct.

5.push the 【☑輸出結構 (Output. geo)】 botton.

The second method are import a figure or import 3D CAD models (*.STL format) into FonSinEM, The detail describe in the following link.

Load 2D Figure Structure

Load 3D CAD Model

Load 3D CAD Model Example

Download the FonSinEM_WriteStructures.zip and then see the example below.
