Welcome to SWIFT: SPH With Inter-dependent Fine-grained Tasking’s documentation!

Want to get started using SWIFT? Check out the on-boarding guide available here. SWIFT can be used as a drop-in replacement for Gadget-2 and initial conditions in hdf5 format for Gadget can directly be read by SWIFT. The only difference is the parameter file that will need to be adapted for SWIFT.
