  We present the TRIDK code, which is written in Python, that solves Triad
Reduced Interactions for a Drift Kinetic system of equations. The
four-dimensional drift kinetic system of equations captures nonlinear
electromagnetic (or electrostatic) interactions for a magnetized plasma at
scales larger than the ion gyroradius. In the TRIDK code, the nonlinear
interaction are modelled using a compound of nested icosahedra-dodecohedra
shells in wave space, which allows to perform computationally efficient
simulations over a large span of scales. This reduced approach captures
essential nonlinear dynamics, while allowing parallel mixing in velocity space
to take place. The intent is to offer a cost efficient way to probe the balance
between linear and nonlinear dynamics, and analyse the interplay between linear
Landau damping and turbulence.
