<div>Hello again Flash users and developers,</div><div>after trying to increase the
resolution as suggested (to no avail), I noticed that when I configure the simulation with a thicker target there is still an angle to the target edge. In the attached picture you can (hopefully) see that the angle of the thicker target's edge is similar to the angle of the thin target which isn't a problem in the case of thicker targets.</div><div>I suspect that the issue is caused by the refinement process, which makes a density gradient.</div><div>I tried increasing the refine_cutoff and derefine_cutoff parameters of the density refine variable but the issue persists.</div><div>I would greatly appreciate it if anybody has any suggestions.</div><div><br></div><div>kind regards,</div><div>Tomer<br></div>
