Hi Guys.
Can you help me setting up a white noise during a few steps on m simulation?
On the section 3.5.5 of the user guide I found this:

<FORCE TYPE="Noise">
  <WHITENOISE> [VALUE] <WHITENOISE/>  
  <!-- Optional arguments -->  
  <UPDATEFREQ> [VALUE] <UPDATEFREQ/>
  <NSTEPS> [VALUE] <NSTEPS/>
</FORCE>

What's the meaning of those white noises? I need to specify one for each direction on three dimension problems? I need to assign that noise to a specific boundary region (a wall, for example)?

Thank you.
Alessandro
