Hi, in mpm99's g2p procedure, when updating the velocity gradient C, why is the square of the "inverse_dx" not used, because in the following formula, it is the square form.

but in the code only one square of inverse_dx was used:

Looking forward to your early reply!

I figure it out! Because in the g2p dpos does not multiply dx:

so that If dpos is multiplied by dx, then multiplying by the square of inv_dx cancels out a dx, so it is only multiplied by inv_dx, not by its square.
