DIS/belt is a time-accurate finite element code for predicting the dynamic response of belt-drives.

DIS/Belt is a specialized version of DIS adapted specifically for simulating belt-drives including automotive accessory drives. This DIS version includes the DIS Solver and special-built pre- and post-processors (DISPRE/Belt - DISPOST/Belt), which allow belt-drive designers to quickly build, analyze, and visualize accessory drives in a user-friendly object-oriented graphical design environment.

DIS/Belt is the only finite element code on the market that can accurately and efficiently model the stick-slip behavior between the belt(s) and the pulleys. This is enabled by the DIS finite element formulation and explicit-time integration solver, which together can maintain time accuracy, and energy/momentum conservation over very long simulation times.
