Help Simple and efficient way to make Obi Fluid rise/lower in a cylinder container

[zkkzkk32312]

Hello,

I am looking for some help to make a simple Oil Fluid project that are

-Contained in a cylinder container for its entire life (liquid in a tank)
-Has the ability to rise up and lower down (to the max height of the tank or to empty tank)
-Uses the less amount of resources because of the limited functionality required as listed above

So far I was able to use the burst mesh emitter to fill the tank when the scene start
but I am getting terrible FPS from the blueprint that I am using (this is my assumption, my blueprint's settings is the problem?)
240 fps vs 20 fps when the sovler is enabled vs disabled


josemendez if you can give me any hint it will be awsome.

thanks,
Zack
