ZMORPH - Engineering Software Tool for Morphing Structural Finite Element Models

ZMORPH (pronounced zee-morph) allows morphing of Nastran structure GRIDs relative to a baseline configuration. The process simply involves encompassing these GRIDs within box primitives and then altering the box corner point coordinates to stretch and/or move these encompassed GRIDs. These box primitives can be considered to be made up of an elastic homogenous material (e.g., rubber) in which the structure GRIDs are embedded. Stretching or moving this material will, in a relative fashion, stretch/move the embedded GRID points.

ZMORPH's Features

• Formulated based on a Boundary Element Method (BEM).



where

{u_i} = displacements at internal structure grid points
[B] = BEM matrix
{u_s} = displacement at BEM box grids

• Reads and Processes MSC Nastran, NX Nastran, and ASTROS Standard Input or Output Decks.
• Outputs New Nastran or ASTROS Finite Element Input Decks based on the newly morphed GRIDs.
• Input based on Nastran Bulk Data Input Format.
• Supports BODY and WING macro-elements and BOX primitives used to encompass structure GRIDs to be morphed.
• WING macro-elements fully support arbitrary airfoil cross-section input (including a built-in NACA airfoil 4/5/6-digit airfoil section generator).
• Fast computation times (seconds for small cases ~5,000 GRIDs to minutes for large cases ~100,000 GRIDs).
• Fully supports ZONA’s Shape Design Variable Linking Scheme (ZLINK).
• Quickly and Easily Morph your Nastran FEA Models.
• Excellent Tool for Shape Optimization (e.g., used within PHX ModelCenter®, VisualDoc®, etc.).

ZMORPH Licensing Information

ZMORPH is available for annual licensing.

Platforms: Win 10 / Win 7 / Vista / XP
Linux: Red Hat / Suse / Ubuntu

License Includes:

• Customer Service (by telephone or email and includes assistance in model input setup if desired). Additional support charged at ZONA Technology's Time and Materials (T&M) rates.
• Software updates as they become available.

Optional ZONA-MV Interface

ZONA has developed program for Windows called the ZONA Model Viewer (ZONA-MV). This program is being extended to allow for a Windows-based option to setup the ZMORPH input deck. The current beta version of ZONA-MV can be provided without documentation upon user request. Note that ZONA-MV provides a host of features (such as loading Nastran Input/Output decks, Plot3D files, Tecplot Files, OpenFSI-UVLM files, etc.) that go beyond the requirements of ZMORPH.
