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., </p> <pre><code>source.sxx = -p; source.syy = -p;</code></pre> <p>Brad. </p> http://www.k-wave.org/forum/topic/units-of-a-stress-source#post-5588 Fri, 15 Jul 2016 14:20:11 +0000 mavheart 5588@http://www.k-wave.org/forum/ <p>Hello,</p> <p>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?</p> <p>Cheers,<br /> Marvin </p>
