~hammett/vlasov/vlad.f is a very simple "Vlasov" code for solving the single-eddy ITG test case... gnuplot v.gp to see plots of the output. Caution: gnuplot appears to have problems if the number of data points in the input files gets to big. 10-17-93 GWH: added f1(v) plots. As one goes to the weak-turbulence regime gamma< (gamma / (kpar vt)) **3 This deserves further study... On the other hand, the above criterion does not mean that 3-moment fluid equations become valid when nu > gamma**3. Rather, this is the criterion for when collisions become important, but not so important that only 3-moments are needed. It look like imag(f1) has two scales, and adding collisions will broaden the resonance scale. By drawing analogies from our earlier work with Stephen Smith, etc., my guess is that the number of moments required to accurately model the result will scale as ((kpar vt)/gamma)**(2/3) *********************************************************** 10-15-93 Bill Dorland found the bug in the velocity part of the definition of omega_*p. Its now working. 10-14-93 First version written.
