    <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>
    </p>
