I wanted to create an effect where an attribute could be transferred and then spread throughout the object - I found the scene on this page which worked great:

However I need to do the same sort of thing inside DOPs - I want to have some highly viscous fluid and melt it with another object then have the heat (or lower viscosity) spread from the point of contact.

 

I've tried using a solver sop inside of a sop solver (connected to the particle motion of the flip solver) however this doesn't seem to work as the solver is using the previous frame so the simulation can never progress (I think thats whats going on). So I basically need to transfer my custom attribute before the pre-flip-solve.

 

Is there a way to do this?

I've attached a scene file with my current progress

 

Thanks,

Mike

David thank you for the file. I changed the parameters to binds and now it seems that the search attribute is propagating and simulating as it should. It wasn't working in H13 i dont know why. Thanks again.
