[FLASH-USERS] Laser across a 1D domain

[Thibault Goudal]

Hello, 
just to contribute to the conversation, in the example1d.par, the geometry is cartesian. I haven't seen explicitely a flash.par input deck including 1D spherical geometry and laser energy deposition. 
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.

Yes, 
In example1d.par the laser is a single ray that propagates along the radius. I am interested in sending a spatially-varying (supergaussian) laser across the radius.

Zach, 

Have you looked at example1d.par in LaserSlab?

Hello all, 
Does anyone know how to simulate a laser impinging across the radius of a 1D radial domain? 
It seems to me that FLASH has no capability of including dimensionality in the laser beam when using a 1D geometry, is this true? 

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. 

Cheers, 
Zach Barfield
