Hi everyone,  
I want to generate an ensemble of Solutions to a differential equation to later study more in depth, so I want to save it to disk (keeping it simple: one file per simulation. Each solution is about 100Mb).

When I try to save the solutions of DifferentialEquations.jl to disk using JDL I get stack overflow errors. Saving just solution.u works and is what I am doing for now, but it loses a considerable amount of convenience due to not keeping everything else that’s in the solution object around.

Any pointers would be appreciated.

See [ANN: BSON.jl, for saving your Julia data](https://discourse.julialang.org/t/ann-bson-jl-for-saving-your-julia-data/9371)

In the [docs](http://docs.juliadiffeq.org/latest/features/io.html#JLD2-1), it recommends using [JLD2.jl](https://github.com/simonster/JLD2.jl) to save the whole solution.

I haven’t tried BSON.jl though. Maybe that’s worth a try.
