: Providing a default.rin ensures that beginner users can run basic 3D-RISM calculations without needing to manually define dozens of complex mathematical parameters from scratch.
: Because 3D-RISM is computationally intensive, the efficiency of the calculation is heavily tied to the settings in this file; overly tight tolerances in the default can lead to significantly longer run times. RTdefault.rin
: The parameters in the default file are generally optimized for common water-based solvent environments (like TIP3P models), which are standard in biological simulations. Considerations for Users : Providing a default
The RTdefault.rin file is essential for researchers using Amber's sander or rism3d.sander modules to perform implicit/explicit hybrid solvation studies. Considerations for Users The RTdefault
: While often overridden by specific user inputs, the default file provides a baseline for the spatial grid density used to map the solvent density.
