How to make this liquid/fluid/melt effect?

Hello,

I was wondering if you guys can help me figure out how to recreate this kind of effect (see the attached image). I’ve tried with the fluid simulator (mantaflow) but couldn’t make it work as well as the dynamic paint modifier (waves).

Image is part of Yan Cook’s work — https://www.behance.net/gallery/90806015/Subatomic-Refraction-2

Thank you!

I might be commenting on something out of my league here but… maybe a combo of these techniques
