Thanks Guy for your precise answer.
Maybe then it would be nice if BF hires both of you full time because there is work for more than one person to do a serious multi FX solver.
I understand however that the funding would need to be bigger and as stable money income than what you and your business partner Dennis make together to be viable.
I think however that what could be shared and discussed by you and Blender/Mantaflow together, is the concept about a new nodal network logic around the different solvers, that should be agnostic and shared by all upcoming FX solvers (with more solvers in the future, internal/external ones) !
