Storing symbolic eoms

[Peter230655]

I am playing around with some simulation, where it takes 10 min to get the eoms.
Is there a way to store / retrieve the symbolic eoms, like one can store the solution with np.savetxt(..) / np.loadtxt(..)?

Thanks for any help!

Yes you can. Here is an example of storing what lambdify generates, for example: https://github.com/mechmotum/bicycle-kickplate-model/blob/master/model.py

You can write sympy objects to disk in a number of ways. This is a question for the sympy and there are many past answers on the mailing list, issues, etc. Search there.

Thanks!
Does not look simple to me, and sympy likely more complicated.
Let me see if I understand it.
