NovaStress is the analysis tool to use when you have quality issues related to stresses.

NovaStress is fully integrated into the NovaFlow&Solid package and gives the ultimate casting simulation solution. The program uses the same meshing technology as NovaFlow&Solid, FVM (Finite Volume Mesh), which exactly describes the original solid geometry. The calculation speed is very fast thanks to a specific calculation method with full contact task.

Finite Volume Method allows the surface of the 3D model to control the shape of the mesh elements on the border of the casting. This creates cubic elements inside the casting and border cells on the boundary of the casting, which generates much faster and more accurate results. FVM also works all the time during the simulation. It is especially important during filling when it is possible to calculate height/width of a metal front. It fills only the necessary fraction of a cell instead of cell by cell which is the case with FDM (Finite Difference Method).

Since launched, our revolutionary adaptive meshing technology has been further developed to save you plenty of time and give you more accurate results. With multi mesh you can switch mesh sizes during both filling and solidification stages.

In the 6.3 version, we gave NovaFlow&Solid a completely new costume (GUI) based on Windows 10 graphical interface. This major update enhanced the appearance and usability of the whole system. This and 41 other updates were made in that release – all because we wanted to make it easier for users to navigate the system.

During the past few years, our parameter optimization feature has been given both a comprehensive functional and visual upgrade including adaptable graphs and Taguchi methods. Much more results fields and auto evaluations have also been implemented.

The gas calculation function takes the gas in mold, the gas backpressure and the venting placement into account when it simulates the mold filling as well as calculating the risk for entrapped air and gas porosities. With the gas bubbles function you can check the effect of different vent and gating placements.

Calculating mold erosion while simulating your castings will help you detect the exact areas where the risk is high. You can then change the flow depending on the result. Mold erosion is possible to calculate for both gravity and high pressure die casting methods in NovaFlow&Solid using both the Grant –Tabakov formula and Normal force component method.

Simulating castings will not only save material and money – but most efficiently time. The timesaving comes from switching mesh in the simulation and during filling in several steps. Where the sections are thick-walled you use a bigger mesh resolution and for sensitive areas you use a finer mesh. In version 6.5 of NovaFlow&Solid (released in April 2021), irregular mesh in mold was implemented which reduces the calculation time for solidification even further. Now, there is no excuse for not using simulation; shortening simulation time is crucial for all foundries to be able to optimize all their castings.
