title: How to edit the source code of Omnet++?
body: <p>When I run Omnet++, it loads <code>.ini</code> and <code>.ned</code> files, and performs a simulation and writes the results in <code>.sca</code> and <code>.vec</code> file. </p>
  
  <p>However I want to modify the source code such that while Omnet++ is running, it loads the input files like every 100 msec and also writes the results after that interval. </p>
  
  <p>How should we modify the code? Is there any other way to update <code>.ini</code> and <code>.ned</code> file while the simulation is in progress without changing the source code?</p>
