[BuddhiLW]

I was able to use ModelingToolKit and OrdinaryDiffEq together to solve the same problem.

I implemented a simple pendulum with friction equation both ways, only had success with ModelingToolKit and OrdinaryDiffEq.

Note that, yesterday, I had solved three problems with DifferentialEquations, which arent currently working, due to this error.

[BuddhiLW]

Now, It's working again. I will close the thread because of it.

I didn't do anything specific to change the situation... I don't know what happened.

Thanks for the support, anyway! I appreciate your works
