<p>I'm not sure I understand exactly what you are trying to do. What
you asking doesn't seem to make sense. The laser will travel along
the radius, yet your super Gaussian profile will be spatially
varying at 90 degrees to the radius, and you want to do it in 1D.
I suspect you want a polar geometry with the laser traveling in
from the radius, right?<br>
<br>
Maybe look at the 2D laser slab? You might be able to put
something together with cylindrical geometry, you could model it
as a circle arc at the end of a tube with the laser coming in from
the longitudinal direction maybe? Otherwise a well refined
Cartesian grid might be better.<br>

<div>I'm not sure that it's possible so far unless mimicing a
spherical geometry with cartesian/cylindrical mesh but not
confident of catching the physics accurently.

<div dir="ltr">Hello all,<br>
<div>Does anyone know how to simulate a laser
impinging <i>across</i> the radius of a 1D radial
domain?</div>
<div>It seems to me that FLASH has no capability of
including dimensionality in the laser beam when
using a 1D geometry, is this true?</div>
<br>
<div>I am using a 1D radial domain because I would
like to simulate the laser heating of a cylinder
of gas with an approximately infinite z-dimension.
I am only interested in the temporal evolution of
the radial profile.</div>
