h2. Name

*fmo* — Fast modelling

h2. Syntax
{panel:|borderStyle=solid|borderWidth=1|bgColor=#FFFFAA}

*fmo* \[*inc*] | \[_nx ny_] \[*x | y*] \[*ibo*] \[*spl* \[*ten*]] \[*vdf*] \[*sdi*] 

{panel}

h2. Description

Generate a fast grid model using interpolation between lines. 

Input to *fmo* must be line oriented polydata. The boundary of the grid will start where a line is first met. 

h2. Arguments

{indent}No arguments, the grid will have the same number of rows and columns as the last grid that set the @nrow @ncol variables.{indent} 
*inc* _xinc yinc_ 
{indent}Create grid model grid with increments _xinc_ and _yinc_.{indent} 
_nx ny_ 
{indent}Create a grid with nx times ny grid cells.{indent} 
*ibo* 
{indent}Include border. Makes an extra rim of defined grid cells along the border.{indent} 
*x* 
{indent}Grid only in x direction. Default is in both direction. Uses the intersection of x or y gridding.{indent}
*y* 
{indent}Grid only in y direction.{indent} 
*spl* \[*ten* _tension_] 
{indent}Will apply a spline as interpolating method. Applying ten with the tension parameter tension having values from 0 - 100, results in a tighter spline. Try low values to get moderate tension.{indent} 
*vdf* 
{indent}Make a grid node if value defined in at least one grid direction.{indent} 
*sdi* 
{indent}Use line with shortest distance to calculate the grid node values.{indent} 

\\
{info:title=Information}
*lst i 117* 
{indent}Will list maximum number of grid nodes that can be generated with *fmo*. Present value for release 4 is 12.2M nodes and for release 5 it is 15.2M nodes.{indent} 
*val i 117* _max\_number\_of\_grid\_nodes_ 
{indent}Will set the maximum number of grid nodes that can be generated with *fmo*.{indent}
