Softellect.OdePackInterop (nuget): C# / F# NET7 interop with FORTRAN ODE Solver DLSODE (https://computing.llnl.gov/projects/odepack, https://www.netlib.org/odepack/) aimed at solving very large systems of potentially stiff ODEs (like chemical systems) where the number of variables is very large (on the order of 10^5 and more).
