Unravelling the statistical geometry of material loops in turbulence with TurTLE

May 05, 2022

A team of researchers from the Max Planck Institute of Dynamics and Self-Organization, the MPCDF and INRIA (Nancy, France) have developed a new open-source computer-simulation code named TurTLE for massively parallel simulations of turbulent flows. The code has recently been employed for studying the geometry of turbulent mixing in fluid flows; the results were published as a “featured article” in Nature Communications.

About the TurTLE code

TurTLE (Turbulence Tools: Lagrangian and Eulerian) implements a number of standard functionality of Fourier-based pseudo-spectral numerical simulations, as well as the corresponding numerical particle-tracking functionality. The package also contains a Navier-Stokes solver, as well as post-processing tools. TurTLE is written in C++ and it uses a hybrid MPI/OpenMP programming paradigm, relying on FFTW3 for an efficient Fourier transform implementation. HDF5 is used for I/O, including for parameter input and output of statistics. CMake is used for compilation and installation.
