piston problem(moving boudary)
 

A cylinder connected with a nozzle. Piston moves and drives the gas flow through the nozzle. I want to solve this gas flow problem using FEM. Does anyone know how to deal with this moving boudary problem? or can you provide any information, papers or books? Thank you very much.

Please Have a look at the SAE's site (sae.org). Also at los alamos lab about KIVA. Its address is gnarly.lanl.gov/Kiva/Kiva.html.

Good Luck
