Entry Price Point: $59,500, which
includes everything except the optional stress module NovaStress. A network license is also available. Overview: NovaFlow and
SolidCV use finite volume method (FVM) a combination of structured finite difference method (FDM) and fractional areas/volumes for geom- etry definition that enables the use
of few elements. FVM calculates 10 times faster than FDM with the same or higher accuracy. Newest Features: Users now can
calculate gas in the mold to simulate backpressure, gas flow and porosity. Since the calculations are quick, they can be used for every part without adding considerable time. NovaFlow also has added auto-reporting and automatic movie making. Software’s Strengths: NovaFlow
and Solid CV are suitable for the common casting processes and ma- terials. The software is particularly beneficial for cast iron (due to its connection with NovaCast’s metal-
lurgical process control ATAS), steel castings and high pressure diecast- ing. The meshing technology also makes the program especially suited to thin-walled castings and large and dispersed pattern layouts. What’s Unique: The auto-
matically generated meshing and calculation speed means all casting methods can be simulated on an ordinary computer. Metallurgi- cal process data from Novacast’s thermal analysis system ATAS can be directly imported and used in NovaFlow and Solid CV, creating a database of information for gray and ductile iron. ■

Entry Price Point: $1,000 for a
trial license Overview: Flow-3D generates
flow and solidification simulation results for casting processes and includes dynamic meshing for easy model setup, a materials property database and extensive post-processing capabilities. Newest Features: Te software now
simulates iron shrink with high carbon content metals to predict the formation of graphite and carbide. It also has a fully-coupled thermal stress model that predicts stresses and distortion within a cast part or die. Tis allows users for the first time to model deformations in the solid state, helping avoid warpage to create better quality cast parts. Te software also offers a sand core simula- tion suite that includes core shooting, core drying, core blowing and core gas defect prediction. Software’s Strengths: Flow 3-D’s filling accuracy leads to accuracy of
solidification by providing the correct thermal profile for solidification. What’s Unique: Treatment of
flowing fluid surfaces is modeled using TruVof, a true implementation of the Volume-of-Fluid method and

the fractional area volume obstacle representation method. Combined with easy-to-use
mesh generation tools, Flow 3-D provides accurate results without sacrificing speed.
