Re: [sparta-users] [EXTERNAL] Spatially dependent surface temperature for surf_collide

[Roshan M. T. <ros...@be...>]

Thanks a lot. Both solutions work for me.

To confirm, these features are not available in the 4/23 release version,
and I'll have to get it directly from GitHub public master.

Thanks
Roshan
