<P><B>Description:</B>

|
|
<P>The execute liggghtsCommand Model can be used to execute a LIGGGHTS command during a CFD run. In above example execute_0 for instance executes "run $couplingInterval" every coupling step. $couplingInterval is automatically replaced by the correct number of DEM steps. Additionally execute_1 executes "write_restart ../DEM/liggghts.restart_$timeStamp" every writing step, where $timeStamp is automatically set.
|
|
</P>
|
|
<H4>These rather complex execute commands can be replaced by the "readLiggghts" and "writeLiggghts" commands!
|
|
