EPS_CONV {Real} 

Convergence threshold for the solution of the Zvector equations. The Zvector equations have the form of a linear system of equations Ax=b, convergence is achieved when Axb<=EPS_CONV. [Edit on GitHub]  
This keyword cannot be repeated and it expects precisely one real.  
Default value:
1.00000000E004 
MAX_ITER {Integer} 

Maximum number of iterations allowed for the solution of the Zvector equations. [Edit on GitHub]  
This keyword cannot be repeated and it expects precisely one integer.  
Default value:
30 

Alias names for this keyword: MAX_NUM_ITER
