UDF for creating motion to a body using a source file.
 
Hi all,

I'm new to CFD and I would very much appreciate a little help with a problem I have at the moment.

I have a container of fluid that a want to apply motion to, which is specified from a source file (text or excel) over a period of time. The data file displacements are all in equal time steps.

I am familiar with the process of applying a UDF, as I have already applied a harmonic wave motion to the body using CG_Motion, but it's the coding involved in this problem that has my troubled as I don't usually use C!

Normally I try to figure these things out on my own, but I'm currently working to a deadline and so I would love if someone would be kind enough to help me out.

Thank you in advance,

John.
