Dear all,
I'm trying to implement a new field equation in CAMB. But due to the extraordinary feature of the field, it shows an unnecessary small oscillation as it evolves.
However, what I need is just the overall amplitude of the field and not the tiny fluctuation, which only results in a significantly slower code. So I want to set a different precision for the equation solver only for my specific field. So, Is there any way to do this?
As far as I understand the code, it seems that the solver allocates the same accuracy parameter for all species simultaneously.
If you could help with this issue, I would appreciate it.

Is there any way to change the accuracy of just one new equation in CAMB?

No, the solver is adaptive. Probably best to derive an analytic approximation equation for the amplitude if that's what you want.
