I want to establish a 2D spherical model. But I found the examples in source of LaserSlab they us cylindrical coordination, but the parameters are (r,z), but what we want is (r,θ)，that means we want a modulate in the direction of θ。 I also found a sphere3D.par in LaserSlab，but the setup command need a Laser3D unit which can't be found in the LaserSlab unit. So, dear kind flash users, could you please instruct me how to establish a 2d spherical laser ablation models? Or is there any model files that can be shared or can be download anywhere? And what is the Laser3D unit?</p><p><br></p><p>Thank you very much</p><p>Best wishes</p><p><br></p><p><br></p><p>Yulin University</p><p><br></p><p>Yun Hu</p></div><span>_______________________________________________</span><br><span>flash-users mailing list</span><br><span>flash-users@flash.rochester.edu</span><br><span></span><br><span>For list info, including unsubscribe:</span><br><span>https://flash.rochester.edu/mailman/listinfo/flash-users</span><br></div></blockquote></div></body></html>
