Detailed Description

template<unsigned int dim>
class coupling::services::ParallelTimeIntegrationService< dim >

Service to manage timeloop of a coupled simulation scenario. Supports sequential or parallel-in-time integration using a Parareal variant, as described in "Blumers, A. L., Li, Z., & Karniadakis, G. E. (2019). Supervised parallel-in-time algorithm for long-time Lagrangian simulations of stochastic dynamics: Application to hydrodynamics. Journal of Computational Physics, 393, 214-228".
