Hi Phil,
I'm not sure what the status of SPH is in the ET (my guess is nothing public), but there is a relativistic formulation of SPH for fixed background spacetimes developed by Rosswog: https://doi.org/10.1088/0264-9381/27/11/114108 In this picture, one would reconstruct the 4-metric from the 3-metric, lapse, and shift to calculate the motion of the particles.
