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 am building a test stand for a client. I need an industrial designer / mechanical designer that has experience with pneumatics. I will be spec'ing out the cylinders, valves, and other important info and I need the designer to build the test stand based on other important info that I provide. I am fine with your choice of most popular 3D modeling CAD programs that are out there (let me know what you have) as I would want the parts and assemblies STEP, ACIS, or other out to myself. I expect a full set of drawings so that I can hand over to the machinist. I use FESTO and SMC products so that any files you will need can be easily downloaded.

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.

The way people shop hasn't changed really that much since the inception of the traditional shopping cart. People go to the Supermarket, use the cart provided for them by their local market, to transfer goods from the store to car to home. I believe most american's to be a convenience oriented people, myself included. The idea came to me one day. I was in Costco shopping right about ready to check out, I noticed there were no more box's available and Costco unfortunately doesn't provide any bags. I thought to myself, now I have to load and unload one item at a time. THIS IS HORRIBLE! This isn't convenient at all! How can I change this? How can I make life easier for myself and the everyday shopper? Convenience and time equals money NO? For now let's call it the Alpha Cart. The Alpha cart was designed to be a point of connection for the consumer. From vehicle to store to vehicle to house with no lifting what so ever. A one stop shop! Alpha's (similar to an ambulance gurney) legs ...
