Release of Chimera Grid Tools Version 1.0

Version 1.0 of Chimera Grid Tools is now ready for your testing and use. Highlights of new features include:

OVERGRIDversion 1.2

Seam curve extraction and cutting plane curve creation capability for surface triangulations in the SEAMCR module.
Hyperbolic surface grid generation capability for triangulated reference surfaces in the SURGRD module.
Ability to generate multiple volume grids with the same stretching function in one run in the HYPGEN module.
A bunch of bugs in OVERGRID were fixed related to avoiding surface normal computations for non-surface entities, uninitialized bounding box at start-up, tmp arrays allocation for mixed sp/dp data, etc.
Periodic index looping for constant J, K, L slices.
Topology analyzer for structured surface entities.
Capability to add comment lines during script generation.
Reporting of individual vertex and face info for triangulated surfaces.

Many minor improvements and fixes were made to the Configuration scripts.

Users on NAS machines

Users on NAS machines have the option to link to pre-compiled executables on server machines. Choose the appropriate installation, and make 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/cgt1.0/bin $path )

setenv SCRIPTLIB /r/octane13/u/wk/chimera/cgt1.0/scriptlib

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

set path = ( /r/octane13/u/wk/chimera/cgt1.0_dp/bin $path )

setenv SCRIPTLIB /r/octane13/u/wk/chimera/cgt1.0_dp/scriptlib

vn, eagle, and newton:

set path = ( /usr/unsupported/bin/chimera/cgt1.0/bin $path )

setenv SCRIPTLIB /usr/unsupported/bin/chimera/cgt1.0/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/cgt1.0/bin/.overgridrc

Want to Get It?

If you are an existing user of CGT and would like a copy of CGT 1.0 sent to you, contact one of us via email: <wchan@nas.nasa.gov> or < rogers@nas.nasa.gov> .

If you have never obtained a copy of the Chimera Grid Tools software package before, you will first have to apply, and sign a Non-Disclosure Agreement.

As usual, bug reports and comments are highly appreciated.
