We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Jim,

I am not using mass scaling. I was able to finally get contact (without using MORTAR) by setting SFSA and SFSB to 100. Was this too heavy handed of an approach? That is, how do I know when the stiffness is too high. It "looks good" to me.

I am now running a timing comparison with MORTAR as you requested and will share when done.
