| adjust |
Fortran_Bool |
.true. |
adjust |
- If adjust is .true., transform from the gyro-averaged dist. fn., g, to the non-Boltzmann part of delta f, h, when applying the collision operator
|
| cfac |
Float |
0.0,1.0 |
cfac |
- Factor multiplying FLR terms in collision operator. 1.0 by default. Set to 0.0 to turn off FLR corrections.
|
| collision_model |
String |
default |
collision_model |
- Collision model used in the simulation.
- default = pitch angle scattering and energy diffusion
- collisionless,none = collisionless
- lorentz = pitch angle scattering only
- ediffuse = energy diffusion only
- krook = use home made krook operator (no reason to use this!)
|
| conservative |
Fortran_Bool |
.true. |
conservative |
- Set to .true. to guarantee exact conservation properties.
|
| conserve_moments |
Fortran_Bool |
.true. |
conserve_moments |
- Set to .true. to guarantee collision operator conserves momentum and energy.

- Set to .true. to compute collisional heating.

|
| special_wfb_lorentz |
Fortran_Bool |
.true. |
special_wfb_lorentz |
- If true (the default) then the wfb is treated in a special way in the lorentz collision operator. This is the standard behaviour. Setting to false has been seen to help an issue in linear flux tube simulations in which the zonal modes at large kx grow rapidly.
|
| split_collisions |
Fortran_Bool |
.false. |
split_collisions |
- If true, then collisions are removed from the Kotschenreuther algorithm and evolved separately. This has the same formal accuracy as including the collisions in the Kotschenreuther advance, but requires fewer calls to the collisions module, and therefore fewer memory redistributes. This gives a speed up of between ~20% and ~60%, depending on processor count.
- If false, the old method is used. This is the default, to prevent discrepancies with old results.

| use_le_layout |
Fortran_Bool |
