<p>This life option is for the users who might want to use their own fatigue
program. The only requirement is that the program writes in ONF-format.
This format can be acquired by contacting <span class = "ph">Dassault Systèmes</span>.</p>
<p>The following variables must also be set in your <span class = "ph">Tosca Structure</span>
configuration:</p>
<pre class = "codeblock">
<code class = "ph codeph">
DRIVER
  driver.LifeSolver.Name = "&lt;name_of_life_solver&gt;"
  driver.LifeSolver.Path = "&lt;path_to_life_executable&gt;"
  driver.LifeSolver.StandardCallArgs = "&lt;list_of_parameters_for_program&gt;"
END_
</code>
</pre>
<p>The optimization run starts like the other fatigue codes with the
solver run, which results are first read into the <span class = "ph">Tosca Structure</span>
database. Then the defined life-solver is called, and the ONF-results
are then read by <span class = "ph">Tosca Structure</span>.
