I am using a CFD program CONVERGE to simulate engine operation. The compression chamber has small leak passages, on the order of 1mm^2, from which the compressed gas leaks during the engine cycle. Modeling these leaks is inefficient due to the small mesh size required, and this slows the simulation computing time dramatically. I would like to hire someone who can modify the CFD code using a "User Defined Function" which will uniformly remove mass from the chamber as a function of time, at a prescribed rate, without physically modeling an orifice to the atmosphere. Please contact me for details.

I need someone to help design how to make a large animatronic animal appear to walk and talk. There are at least 10 leg joints that need to be controlled however, there is a wheeled base between the legs that actually propels the animal. The leg movement (speed) just needs to match the speed of the base. There are also some motors in the head for mouth and ear movement. The mouth needs to be somewhat synced with a prerecorded audio routine (animal talking). The animal is in Philadelphia so it would be best to hire someone in that general area. Thx.
