NAGSIM.3D - Version 1.5

NAGSIM.3D- is a general purpose finite element analysis (FEA) software program for the computer simulation of three dimensional metal forming processes. NAGSIM.3D can simulate large plastic deformation of the part. Its powerful solver uses a modified tetra element that allows automatic meshing of complex parts.


Eliminate Trial & Error in Forming. NAGSIM.3D can be used to:
--- - Predict metal flow
--- - Predict non-fill conditions
--- - Predict defects and high stress / strain areas
--- - Optimize the preform shape
--- - Determine mechanical properties of the formed part
--- - Determine influence of lubricants
--- - Improve tool life

NAGSIM.3D's graphical user interface is tailored for simulating metal forming operations. It is very user-friendly and intuitive to use. NAGSIM.3D provides a complete insight into the forming process. The results include: Material flow, stress distribution, strain distribution, formation of laps, force distribution and contact between the part and the tools. Animation presents a clear visual of the forming operation.

Integration with NAGSIM.2D – NAGSIM.3D has the capability to bring in results of NAGSIM.2D simulation for the previous operation including strains. The program converts the 2D results into 3D by revolving the 2D section about the Z-Axis. This feature is extremely beneficial for Users that form parts in multiple operations. The initial 2D operations can be analyzed in NAGSIM.2D and the final operations involving 3D geometry are simulated in NAGSIM.3D program.

Preprocessor – NAGSIM.3D provides a simple method of importing geometry of the tools and the initial blank drawings into the program.
