<div dir="ltr">Hi Yaoxing,<div><br></div><div>You would need to edit the "Simulation_initBlock.F90" for your simulation so that velocity is initialized to something not zero. You can use the "Grid_putPointData" routine as is done in LaserSlab:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p class="MsoNormal"><span lang="EN-US">I am simulating a laser pulse irradiated on a droplet target based on the LaserSlab simulation. I am wondering that if the target can have an initial velocity before the laser pulse arrives?</span></p>

<p class="MsoNormal"><span lang="EN-US">If so, could you please tell me how to set the target initial velocity?</span></p>
