• Keyword descriptions

  EPS_CONV
  	EPS_CONV {Real}
  	Convergence threshold for the solution of the Z-vector equations. The Z-vector equations have the form of a linear system of equations Ax=b, convergence is achieved when |Ax-b|<=EPS_CONV.
  	This keyword cannot be repeated and it expects precisely one real.
  	Default value: 1.00000000E-004

  MAX_ITER
  	MAX_ITER {Integer}
  	Maximum number of iterations allowed for the solution of the Z-vector equations.
  	This keyword cannot be repeated and it expects precisely one integer.
  	Default value: 30
  	Alias names for this keyword: MAX_NUM_ITER
