[Sidefx-houdini-list] Invert metaball kernel effect with force SOP

Hi all.
This is somethign that I have been wondering how to do for a while, but I
cant get any solution.
Probably is somethign fairly easy but seems that there is no way invert the
kernel function for a metaball.
For instance, if yoyu use a force SOP to define a radial force for the
metaball, this force is stronger the closer you are to the mball kernel.
Is there any way to do the oposite? Make the force stronger in the mball
boundaries and then disipate it as you get closer to the kernel.

Un saludo
Best Regards
Pablo Giménez
