Using a set of 45 massive galaxy cluster zoom simulations, run with both the EAGLE and BAHAMAS models, we have looked at the effect of changes in the underlying SPH flavours (e.g. increased mixing), and sub-grid physics (e.g. changes in feedback mechanisms) on hydrostatic mass estimates when using mock X-ray data and a proxy for an SZ signal. We have also seen how including the non-thermal pressure in the calculation of mass leads to a less biased result.
