GSOC'25: Classical Mechanics: Implement Specific Forces and Torques

[Srivathsan Ram]

Dear Sympy Team,

I am very interested in the implementation of Specific Forces (specifically Aerodynamics and Friction). I have a strong background in physics - being a member of my country's physics olympiad team and having a innate curiosity about the use of computation in physics. I am well-versed in numerical models such as the Newton-Raphson method, Verlet integration, etc.

At the moment, the Aerodynamics portion of multibody dynamics is limited to the Bernoulli Equation for modelling aerodynamic forces.

My proposal entails the following additions to the library in order of priority:

1. Boundary layer modelling: Laminar and Turbulent flow separations

2. Flow modelling: Source, Sink and Vortex using gradient vector

3. Airfoil Modelling: Possible modelling of NACA 4-5 digit airfoils to calculate lift coefficients

Could I check if these improvements are in line with what Sympy has in mind for future iterations of the Aerodynamics method and if there are any possible suggestions or additions that are recommended for my proposal?

Thanks a lot and Regards,

Srivathsan Ram

Dear Srivathsan,

I have used sympy.physic.mechanics for a while, but I never came across its Aerodynamics portion - but then again, I never looked for this.

Could you point out to me, where you found this?

Thanks,

Peter

Hi Peter,

You are right that aerodynamics module does not exist at the moment. Rather it is a recommendation on how to model aerodynamics using the Bernoulli Equation as mentioned in: https://moorepants.github.io/learn-multibody-dynamics/loads.html#aerodynamic-drag

Regards,

Thanks!

So at least I did not overlook it, due to my age! 😊

Dear Srivathsan,

I don't think these forces you describe fit well with what we currently have.
