For getting the large scale structure, the full box was simulated with 256^3 and 128^3 (dark matter) particles. The initial conditions were set up according to a WMAP 3 power spectrum and normalization. The constraints for simulating the Local Universe were generated as a 256^3 mesh of overdensities.
The full box was simulated with dark matter particles only.
