   Hello,

   I was wondering: When using the new solid-body simulation, I have to have my input as a stress-source even if the source is located in a liquid part of the medium. What unit of measurement does my input signal have to have for such a source?

   Cheers,
   Marvin

   Hi Marvin,

   Stress is defined in units of pressure (Pascals or N/m^2). For example, if you wanted to run a fluid simulation using the elastic code, you would set the normal components of the stress to the negative of the pressure, i.e.,

   source.sxx = -p;
   source.syy = -p;

   Brad.
