Help with Solving PDE System with DAE in MATLAB

on 30 Jul 2025
I hope you're doing well. My name is William. I’m currently working on a problem and was hoping you might be able to help. I have a system of PDEs, but one of the variables does not include a time derivative (e.g., no ∂u/∂t), even though the variable depends on both time and space. I'm not sure how to approach solving this in MATLAB. I’ve been able to implement it in gPROMS, but translating it into MATLAB has been challenging.
I tried to follow your DAE method, but my variables depend on both time and space—not just time—so I’m unsure how to proceed. If you could offer any guidance or point me in the right direction, I would greatly appreciate it.
Thank you for your time and support.
Best regards,
William
