<html><head><meta http-equiv="Content-Type" content="text/html charset=us-ascii"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">Hi,<div><br></div><div>I am trying to setup a simulation that looks at RT growth of seeded perturbations on a laser-accelerated foil. The foil parameters I'd like to implement is a 21um thick foil with a 0.27um sinusoidal amplitude perturbation on it. I have altered the LaserSlab simulation initBlock to do this and I can successfully create a 21um thick foil with a 2um perturbation, but as I try to make the perturbation smaller, the foil entirely disappears from the domain. I have tried to change the lrefine_max parameter to get the resolution I need, but have been thus far unsuccessful at getting down to the sub micron level that i need to run the simulation. I also ran the ./setup with nxb=32 and nyb=32 to try to get at the problem, but still to no avail.</div><div><br></div><div>The domain is rather large, 300 um X 1100 um, due to the fact that I need to have some computational space given to the laser-plasma interaction and to allow the foil to accelerate and move during the simulation.</div><div><br></div><div>Any thoughts on how I could better implement my problem?</div><div><br></div><div>Cheers,</div><div>Mario </div><div><br><div apple-content-edited="true">
