&GAS: RESET


item

The following items can be reset:
ATTACHMENT-COEFFICIENTS
Resets the attachment coefficient and defaults the interpolation and extrapolation methods for this item.
CLUSTERING-DATA
Resets the cluster size distribution, whether derived from Heed, from a Landau distribution or from a table of cluster sizes. Also resets the mean number of clusters per cm as entered with the PARAMETERS statement.
DIFFUSION
Equivalent to LONGITUDINAL-DIFFUSION, TRANSVERSE-DIFFUSION and DIFFUSION-TENSOR combined.
DIFFUSION-TENSOR
Resets all 6 components of the diffusion covariance matrix and defaults the interpolation and extrapolation methods for this item.
DRIFT-VELOCITY
Resets all 3 drift velocity components, i.e. the component parallel with E, the component parallel with the part of B transverse with respect to E and the component parallel with ExB. Also defaults the interpolation and extrapolation methods for these items.
GAS-IDENTIFIER
Sets the gas identifier to a blank string.
ION-DISSOCIATION
Resets the ion dissociation coefficients and defaults the interpolation and extrapolation methods for this item.
ION-MOBILITY
Resets the ion mobility and defaults the interpolation and extrapolation methods for this item.
LONGITUDINAL-DIFFUSION
Resets the longitudinal diffusion and defaults the interpolation and extrapolation methods for this item.
LORENTZ-ANGLES
Resets the Lorentz angles and defaults the interpolation and extrapolation methods for this item.
TABLES
Equivalent to combining ATTACHMENT-COEFFICIENTS, DIFFUSION, DRIFT-VELOCITY, LORENTZ-ANGLES and TOWNSEND-COEFFICIENTS.
TOWNSEND-COEFFICIENTS
Resets the Townsend coefficient and defaults the interpolation and extrapolation methods for this item.
TRANSVERSE-DIFFUSION
Resets the transverse diffusion and defaults the interpolation and extrapolation methods for this item.
