Dear forum members,

I am new on matlab and I have been looking recently for a toolbox to perform fluid dynamics simulation.

I was wondering if the PDE toolbox was complete enough to perform fluid mechanics simulation ?

If some forum members have experience with this PDE toolbox or with fluid dynamics simulation on Matlab, I would be happy to have some feedback to know where to start !

Thanks in advance for your help.

Regards,

Andrew

To the best of my understanding the PDE-toolbox are complete enough for this. (However, I've generally struggled too much to use it to solve coupled PDEs)

Although not available in the PDE toolbox, for fluid dynamics simulation in MATLAB you can use the CFDTool GUI toolbox which features built-in integration with the OpenFOAM and SU2 CFD solvers.

Hi Andrew,

The PDE Toolbox is a finite element solver. It solves equations of the form: https://www.mathworks.com/help/pde/ug/equations-you-can-solve.html. As far as I know, Navier-Stokes equation can't be cast into this form without putting all the nonlinear terms to the right-hand side. So, PDE Toolbox might not be adequate for fluid mechanics simulation, in general.
