<p>Hi,</p>
<p>To answer your question I will say all depends on exactly what
you want to do.</p>
<p>1. FLASH is mainly an hydro / MHD code. I don't think the
approximation relative to those approaches are true at a the
nanometer scale.<br>
</p>
<p>2. If you want to simulate other material you can use:<br>
- multi-species simulations and defined the properties of each
species<br>
- tabulated equations of state and opacities<br>
- you can also check the burn unit if you are interested in
nuclear reaction<br>
</p>
<p>3. To define the laser you need:<br>
- a target: position and dimension<br>
- a length: position and dimension<br>
- an angle (ed_semiAxisMajorTorsionAngle_1)<br>
With this parameter you can define any laser incidence you may
need.<br>
</p>
<p>Best regards,<br>
