An innovative radiative transfer code (LIME) using adaptive gridding that allows simulations of sources with arbitrary multi-dimensional (1D, 2D, 3D) and time-dependent structures, ensuring rapid convergence.
•Unique tools for modeling the polarization of the line and dust emission, information that will come with standard ALMA observations.
•A library of commonly used analytic/semi-analytic models as well as a comprehensive graphical user interface.
