= Why is my model using 2020 HPC twice as slow as 2018 HPC?=
The change in runtime can be due to different timestepping applied with the new default - mesh size insensitive turbulence model - Wu instead of Smagorinsky. NotTo allconfirm HPCthis models will show an increase in runtime when changing fromis the 2018case, totest therun 2020your releasemodel -with models that are controlled by the wave celerity or velocity control numbers2020release and not the diffusion control number are likely to be similar in runtime.
