SPECT3D is a multi-D collisional-radiative spectral analysis code designed to simulate the atomic and radiative properties of laboratory and astrophysical plasmas.

SPECT3D is generally used to post-process the results of radiation-hydrodynamics simulations or particle-in-cell (PIC) simulations. SPECT3D computes spectral properties (emission and absorption) and ionization properties for LTE and non-LTE plasmas.

In designing SPECT3D, a strong emphasis has been placed on making it easy to use. It features a user-friendly graphical interface for setting up problems, monitoring the progress of simulations, and viewing results.
