Input Parameter

Physical Definition

The scaling factor by which the layers geometrically change thickness.

  • If RLAY < 1: Layers will geometrically decrease in thickness
  • If RLAY = 1: Layers will not geometrically change in thickness
  • If RLAY > 1: Layers will geometrically increase in thickness


Davinci Usage

Davinci Definition:
  • Same as Physical Definition
Values:
  • Input = Real Value Parameter
  • Units: Unitless
  • Range = Greater than 0
  • Default Value = 1.2
Input Parameter Name:
  • RLAY


KRC Usage

KRC Definition:
  • Same as Physical Definition
Values:
  • Input = Real Value Parameter in F10.2 FORTRAN format
i.e. Floating point value, with a field width of 10, including leading blank spaces, plus or minus sign, decimal point and 2 integers after the decimal point.
  • Units: Same as Davinci
  • Range = Same as Davinci
  • Default Value = Same as Davinci
Input Parameter Name:
  • Same as Davinci
Example:
See the default master input file as an example: master.inp
