charlestan88 New Member Dean Smith Join Date: Oct 2013 Posts: 8 Rep Power: 13	I need to simulate a simple model of an object moving down into a fluid. Essentially a force pushing an object lower into a fluid in a container of sorts and eventually stopping after travelling a specified distance in time. Is it possible to write a UDF for this? i need to essentially simulate the pressure on the walls of the container and fluid from this motion. Completely new to UDFs and have no idea where to get started.
