Out of memory problem using ODE solver

Hi everyone,

I have the problem of out of memory in a time domain stiff simulation using ODE15s. What I have tried to solve the problem is the well-known discretizing the time range but doesn't work and I still face the problem. Any idea?

many thanks

Did you try whether a nonstiff solver really doesn't work ?

These solvers need much less memory.

Best wishes

"Out-of-memory" is treated in the same way every time:

• Install more RAM
• Free unused memory
• Increase the virtual memory
• Install even much more RAM

But in addition post the complete error message, most of all the line, which causes the error. Sometimes the memory is not the problem, but simply a type as: rand(1e6) instead of rand(1, 1e6).
