Thank you very much for the birthday wishes which were nice to read!
I've had a nice day at home with my family. The UK public sector strike was on a good day for me, because it meant Leo's school was closed. Nicole doesn't go to school on Wednesdays anyway so that meant we were all at home!
I have not worked today of course but recently I've been continuing with the tyre model. Specifically I've been improving the non-real-time tyre carcass model so it can correctly predict the stiffness in various directions and contact patch width / length for a given deflection at various camber amounts and pressures, for all different tyre sizes. It's a long time I've been on that, I know, but the gradual improvements in that will make the real-time model much closer to reality, so I think it's the right thing to do.
Thanks again for the birthday wishes!
