CGT 0.9 Release Announcement

Release of Chimera Grid Tools Version 0.9

Version 0.9 of Chimera Grid Tools is now ready for your testing and use. Highlights of new features include:

OVERGRID version 1.1

significant efficiency improvement by eliminating copy of entities on disk. Double precision entities are now stored in-core. Grided functions are now internal.
average cell size grid diagnostic function to highlight mismatches in grid resolution in overlapped zones.
iblanks and Jacobians statistics under the DIAGNOS module.
new preliminary capability to handle triangles database. Functions supported include read/write files in CART3D or FAST unstructured formats (files must have .tri and .fst extensions, respectively) view in wireframe or shaded modes, grided functions for reverse, mirror, scale, translate, rotate.

An optional input parameter IFCC (after IAUC) was added to SURGRD to turn on/off automatic following of interior control curves.
A multiple concatenation bug was fixed in GRIDED. Checks were added for output filename validity.
Fixed bugs in RunPeg and RECURV
Added a folded-surface option to SMOGRD
Users on NAS machines have the option to link to pre-compiled executables on server machines. Choose the appropriate installation, and make both both of the following additions to your path and to your environment. To access these directories on vn, eagle, or newton[1234], you must be added to our Access Control List (ACL). Contact Stuart Rogers, rogers@nas.nasa.gov, to be added. (If you are a user outside NASA, you will have to sign a non-disclosure statement first). These examples are for /bin/csh users:

SGI workstations on .nas.nasa.gov network, single precision:

set path = ( /r/octane13/u/wk/chimera/cgt0.9/bin $path )

setenv SCRIPTLIB /r/octane13/u/wk/chimera/cgt0.9/scriptlib

SGI workstations on .nas.nasa.gov network, double precision:

set path = ( /r/octane13/u/wk/chimera/cgt0.9_dp/bin $path )

setenv SCRIPTLIB /r/octane13/u/wk/chimera/cgt0.9_dp/scriptlib

vn, eagle, and newton:

set path = ( /usr/unsupported/bin/chimera/cgt0.9/bin $path )

setenv SCRIPTLIB /usr/unsupported/bin/chimera/cgt0.9/scriptlib

OVERGRID users on NAS workstations also have to copy the following preferences file and put it in the user's home directory:
/r/octane13/u/wk/chimera/cgt0.9/bin/.overgridrc
