1.5.4 Define conductor properties Set properties of material, conductor and point. The nodal properties must be set ahead. Menu “Properties”→ “Point”→ “Add Property” Figure 1-74 Nodal property dialogue box In nodal property, we set the point charge density as 100C/m . In the Problem definition, we have set the depth to 1 mm. So the point charge has 100C/m* 0.001m= 0.1C. Sphere capacitor Sphere Table 1-8 Formula Figure 1-75Sphere Capacitor 7 1.5.5 Add materials to the model We set εr „air‟ as 1. Figure 1-76Material property 7 http://upload.wikimedia.org/wikipedia/commons/3/3f/Spherical_Capacitor.svg
1.5.6 Define conductor properties The outer shell is connected with ground, so we set it as Gnd. Select the outer shell and press Space bar to set the further properties. Figure 1-77Attach conductors to their properties First, select the node in the center of circle by left clicking on it under function ”Operation on node”. Then press Space bar to pop the dialogue box, where we can define the property of a node. Select “Nodal Property” to Q, which we have defined already. Figure 1-78Attach node to its property 1.5.7 Place block labels and associate them with materials. Set the only block as “air”. 1.5.8 Generate mesh and run FEA The mesh size was chosen by triangle.
