Following 3D topologies are allowed:
Description |
Typical look of imported part |
With the background region* in QuickField |
1. Single solid body |
This is a single body constructed as a result of substraction of spherical segment form a cube. |
|
2. Single solid body
|
A cube has inclusion (other body) of a cone shape (marked green). |
|
3. Multiple solid bodies with different permittivities not touching each other.
|
Cylinder and cone objects not touching each other. |
|
4. Multiple solid bodies of the same permittivity which are touching each other
|
Cylinder and cone objects in contact. |
* Background region - rectangular box enclosing the whole model at the predefined distance from it.
These topologies are currently not allowed:

Suggested workaround |
Single solid body with several inclusions which are touching each other |
The grey cube includes the gray cylinder and green cone that are in direct contact with each other. |
The universal workaround is adding the small gap between the touching objects. This would convert problem to one of the cases from the table above.
|
Multiple solid bodies of the same permittivity are touching each other with boundary conditions set in between. |
Cylinder and cube are touching each other. There is a boundary condition to be set at the contact surface (marked green). |
|
Multiple solid bodies made of materials with different permittivity are touching each other. |
The grey cube touches the green cylinder made of different material. |
