OPTIMISATIONsection, a new command,
GRAVITY, and further arguments in the
ROWSlisting, have been added. As a result, compact format cell datasets written by earlier versions, should be re-created.
FORCESinstruction has been further improved. It now computes the profile of a wire, taking the dependence of the forces on the wire displacement, and also the gravitational force, into account. In addition, the instruction can now deal with certain types of collective wire movement. The format of this statement has changed: consult the help file for information.
MULTIPOLEcommand has been corrected. The command now also prints the 0th order term.
Plotting of the distortion of the magnetic field, due to the difference in susceptibility of the wire material and the gas, used to be disabled by mistake; this has been corrected now.
KEEP-RESULTS, has been added to the
CHECK command to save the surface field in a
The warning on non-convergence issued by the routines that compute the transverse and longitudinal diffusion in Magboltz is now only printed if debugging has been requested. The non-convergence is genuine, but the back-up method to calculate these quantities seems to function satisfactorily.
Correction in the gas table plotting routine to handle cases correctly where both the Townsend and the attachment coefficient are uniformly zero.
SINGLEcommand didn't return the attachment coefficients correctly. The command has been fixed.
ARRIVAL instruction now accepts an option
KEEP-RESULTS to save the x(t) relation as a
set of matrices.
PLOT_AREAprocedures now respect logarithmic scaling.
INQUIRE_MEMBERto test the existence of a member within a library;
PLOT_LINEnow accepts an option
SMOOTHto plot a smooth line through a set of points.
On UNIX systems, the shell used for executing UNIX commands
is now by default set to the shell from which Garfield was started.
A shell can also be selected explicitely by the user using the
