Presentation of outcomes from the Computational Fluid Dynamics method working group.

Computation Fluid Dynamics working group table of issues;

NO Consistency of Tyre RRC
3g/km Extension from Cal. ? or Test CO₂ value ?
How to develop f₀ and f₂ with fixed f₁ ?
Adjusted f_0,L and/or f_2,L are bigger than f_0,H and/or f_2,H ?
Huge Error when adjusting f_1,L to f_1,H

During discussion in WLTP/DTP, 40 CFR Part 1066 was not finalized yet. Therefore, the values from text in 2011 were used in GTR15. However, the value in CFR were changed to 1.0% from 0.5%. This changes were made to harmonize with other regulations and also because CH-DY manufacturers could not comply with this value.
