    3DMAGGS has the capacity to generate symmetry planes, ellipsoids, spheroids, cylinders, and singular poles to close off a domain.

Comments:

    Please note that this software was developed as part of a support services contract from Lockheed Martin to NASA. For this reason, the software is maintained and distributed by Lockheed Martin, but approval to disseminate software lies with NASA. Hence, the inclusion of NASA for contact and organization information.This code is designed to replace the GRIDGEN3D code by offering comparable capabilities at 10 times the speed of execution. It offers low precision machine flags to control round-off error creep, as well
    as preconditioning of implicit source term controls with explicit source terms.
