Assignee: TRIAD NATIONAL SECURITY, LLC
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A computer-implemented method, comprising:
providing a numerical simulation solid mesh comprising a plurality of solid nodes and a numerical simulation fluid mesh comprising a plurality of fluid nodes; and
performing a numerical simulation with the solid mesh and fluid mesh including:
determining a fluid-solid interaction between the fluid mesh and the solid mesh at a time step by:
(i) immersing boundaries of the solid and fluid meshes,
(ii) computing current corrected fluid and solid velocities using an interaction parameter applied to an intermediate fluid-solid relative velocity, and
(iii) computing a fluid-solid interaction force based on the current corrected fluid and solid velocities;

wherein the determining the fluid-solid interaction comprises an implicit determining within an explicit fluid solver of the numerical simulation;
wherein the explicit fluid solver is integrated, as opposed to coupled, into a combined finite-discrete element method (FDEM) solver of the numerical simulation.
