Synopsis

Description

This statement is used to specify the material of rectangles in a rectangular mesh. Region statements should follow line statements. Every element must be given some material, so at least one region statement is required for each rectangular mesh.

xlo, ylo, zlo, xhi, yhi, zhi: The bounds of the rectangle being specified. The <string> value should be one of the tags created in a preceding line statement. X values always have to be specified, but higher dimensions are optional dependening on the structure being set up.
MaterialType: The material of this region.

Examples

region silicon ylo=left yhi=right xlo=surf xhi=back

This line would make the a silicon block within these specified tagged lines.

region metal=base ylo=left yhi=right xlo=surf xlo=surf

This creates a one dimensional metal region along the top of the device. This would be useful for creating a contact for device simulation
