Hello, This is Salah Soliman.
I see that you are in hurry, and I won't use that, I can implement two-dimensional diffusion equation using python, in less than 2 hours.
Also all documentation can be done in less than 2 hours, so you will take your project in 4 hours.
I forgot to mention that I'm a Senior Mechatronics Engineering student, and I have hands on experience in thermodynamics and heat transfer through projects.
Note: The price is negotiable.
Regards,
Salah Soliman
