We initialize our simulations using transfer functions, $T_{\\mathrm{f-NCDM}}(k)\\equiv\\sqrt{P_{\\mathrm{f-NCDM}}(k)/P_{\\mathrm{CDM}}(k)}$ (where $P(k)$ is the linear matter power spectrum), with an initial suppression similar to thermal-relic warm dark matter (WDM) followed by a constant-amplitude plateau.
