Flare Quantum Mechanics

State-of-the-art Quantum Mechanics (QM) calculations for your ligands

Based on the popular Psi4 implementation, the Quantum Mechanics module in Flare features robust pre-defined settings novel users can trust, as well as a choice of different levels of theory for more experienced users.

  • Run QM experiments to optimize the input geometry and calculate the QM energy and properties of ligands, conformations and poses
  • Use QM to calculate and display the molecular electrostatic potential for your ligands
  • Calculate and visualize the QM torsion profile for selected rotamers in ligands of interest using a friendly wizard-driven workflow
  • Optimize calculation time by using the Cresset Engine Broker™ to connect to a local cluster or cloud computing facilities
