For an additive source, you can think of this as being set to zero. For a dirichlet source, the boundary condition stops being enforced.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/behaivor-of-sourcep-when-the-number-of-points-is-not-equal-to-kgridnt#post-6954 Mon, 08 Jul 2019 18:18:36 +0000 Patrick 6954@http://www.k-wave.org/forum/ <p>Hello,</p> <p>I am using a time-varying source and wondering what the behavior of <code>source.p</code> is when it has a number of points not equal to the number of time points on the grid. For example:</p> <p>If <code>source.p</code> has <code>10</code> time points, but <code>kgrid.Nt = 100</code> does the ten points in <code>source.p</code> correspond to the first <code>10</code> time points on <code>kgrid</code>, in which case I assume the rest of <code>source.p</code> would be zeros? Or are they evenly spaced out, in which case maybe they are interpolated?</p> <p>Any help is very much appreciated. </p>
