3D simulation software reduces modeling time.


New version 7.1 of Moldex3D injection molding injection molding
n.
A manufacturing process for forming objects, as of plastic or metal, by heating the molding material to a fluid state and injecting it into a mold.
 simulation software Simulation software is based on the process of imitating a real phenomenon with a set of mathematical formulas. It is, essentially, a program that allows the user to observe an operation through simulation without actually running the program.  offers faster calculation, easier meshing of large models, improved multi-component molding simulation, and a new material data base. Moldex3D is developed by CoreTech System in Taiwan and is offered here through EPS (Encapsulated PostScript) A PostScript file format used to transfer a graphic image between applications and platforms. EPS files contain PostScript code as well as an optional preview image in TIFF, WMF, PICT or EPSI, the latter being an ASCII-only format.  Flotek, Naperville, Ill.

New developments include the ability to work with bigger models using parallel computing Solving a problem with multiple computers or computers made up of multiple processors. It is an umbrella term for a variety of architectures, including symmetric multiprocessing (SMP), clusters of SMP systems, massively parallel processors (MPPs) and grid computing.  and Windows Clustering capability. With these two techniques, multiple PCs can be utilized to solve a single simulation, speeding results by up to 400% or even more. The built-in material database has a new interface for direct access to the Material Data Center's internet materials database, which is supported by more than 30 resin suppliers.

Users can split a solid-mesh block model to reduce memory requirements for large models. Moreover, a tetrahedral tet·ra·he·dral

1. Of or relating to a tetrahedron.

2. Having four faces.

 mesh can now be generated while using 30% to 50% less memory. Other improvements include an auto thickness detector for shell (midplane) analysis.

The newest version is also able to more accurately model multi-component molding, such as insert or overmolding. It supports both shell and solid modules, and models heat dissipation and warpage according to the different material characteristics. Other new modules interface directly to structural analysis programs such as Ansys and NEiNastran. Tel: (630) 778-7773 * PTDirect: 838WD
