  We present a technique to represent anisotropic heavy-quark potentials as
effective potentials. This involves employing an effective screening mass
linked to the quantum numbers $l$ and $m$ of a specific state. Our approach
utilizes the resulting 1D effective potential model, enabling the solution of a
1D Schr\"odinger equation. Remarkably, this model accurately reproduces the
energies and binding energies of low-lying heavy-quarkonium bound states in 3D,
including the differentiation of various p-wave polarizations. The derived 1D
effective model offers a means to incorporate momentum anisotropy effects into
simulations of heavy-quarkonium dynamics in the quark-gluon plasma within open
quantum systems.
