Hey there, I have plenty of experience in formulating algorithms and writing codes for numerical computing, be it Finite Element or Finite Difference. In fact, in my master's program, I wrote my own FEA code for my thesis which was based in evaluating a new material constitutive relationship.
I can code it in either matlab or python as they are the easiest languages for fast prototyping.
Please let me know your exact requirement. Also, it would be nice if you could open your chat access to me so that we can discuss your project in detail.
Thanks!
