Same ramps not producing same results

[derchow]

Hello,

I have been running into an issue where two identical plasma profiles are producing different results. In one simulation, there is a uniform density profile where n0 = 1.0e18 and “density” is set to 1.0. In another simulation (also uniform plasma profile), n0 = 1.0e19 and “density” is set to 0.1. The two simulations have otherwise identical parameters (adjusted for the different kp^-1). Mathematically, these are identical ramps and should give identical results, however, they are not. Is it possible to cross density regimes in such a manner, and if so, what is the correct way to go about it? The input files used are being attached.
