description</a></h2>
<p>Overrides normal mode of pre-calculating and storing bond pair-to-node a nd kernel atom-to-node matrices. If activated, will calculate elements of t hese matrices during repeated calls of field computations (i.e. "on-the-fly") and not store them for future use. <br/>
on flag is optional - if omitted, on_the_fly will be activated for the s pecified matrix. Can be deactivated using off flag. <br/>

<p>Must be used with the hardy/field type of AtC fix ( see <a class="el" href="man_fix_atc.html">fix atc command</a> ) </p>

default</a></h2>
<p>By default, on-the-fly calculation is not active (i.e. off). However, code does a memory allocation check to determine if it can store all needed bond and kernel matrix ele ments. If this allocation fails, on-the-fly is activated. <br/>
