- Problem: Even after the last fix, there are still nan/inf values in the fstat files. These nan's in the fstat files cause nan's in the stat files.
Solution: Dariel Hernández Delfin: Check that the nan values in the fstat files are for contacts with zero force (i.e. they can be ignored). Remove them from the fstat file (e.g. sed -i 's/nan/0/g' *.fstat). Then your stat files should be without nan's - Problem: f^nu-phi^nu vs phi^nu plots are incorrect: f^nu-phi^nu should be 0 at phi^nu equal to 0 and 1, and the plots for spheres and ellipsoids should be point-symmetric (because f^sp+f^el=1, phi^sp+phi^el=1).This must be a bug
Solution: Dariel Hernández Delfin should find the bug. - Dariel showed me plots that show a quite clear correlation between segregation strength and contact overstress f_c^nu-phi^nu, not with kinetic-overstress.
To show this clearly: Dariel Hernández Delfin plot overstress f^nu-phi^nu as a function of aspect ratio (for both kinetic and contact). You could limit the data to phi^nu values between 0.4 and 0.6 to get reliable data for such a plot. - Problem: The overstress behaviour seems different near the drum wall
Solution: Dariel Hernández Delfin color the data taken from near the wall differently, so we can distinguish. - Problem: Raul cannot see the notes I think
Solution: Thomas Weinhart Get Raul to sign up to confluence.

- Plots are now symmetric. Data shows two competing mechanisms, f^c-f^k and f^k-phi.
- We should add Chute data
- Suggestion for Mercury by Raul: estimate contact point of superquadrics with spherocylinder
- Suggestion by Raul: You can define quite general shapes using spherocylinders with a variable radius.
2020-11-4 Meeting notes Dariel
- Note: Deepaks paper predicts segregation even in the non-sheared regions; there is a shear-rate dependency missing; so we should only consider the sheared flowing layer. (There is a draft paper by Deepak showing dependence on I)
- V_r shows no flip in segregation directions; but, see above, it should be averaged only over the flowing layer.
- Dariel Hernández Delfin redo the plot. Also replot numerator and denominator separately.
