If you're looking to perform a thermal analysis for the cyclic heating of molds for container forming processes, our meshless CFD software NOGRID points is an excellent solution. It delivers detailed insights into the thermal behavior of molds under cyclic heating conditions, allowing engineers to optimize mold design and improve product quality.
Using a geometrical model - either imported from your CAD system or created with our CAD preprocessor COMPASS - you can quickly generate a computer model of a specific geometry. Compared to traditional mesh-based methods, this process is significantly faster and allows you to analyze the thermal characteristics of the design in advance.
Periodic heat loads or cyclic heating of molds are very common in many industrial processes. Beginning with a cold, solid mold, the temperature gradually rises over time with each cycle until a steady-state temperature distribution is reached within the mold. At that stage only the temperature at boundaries where the heat load is applied will change with the given period.
Simulation of cyclic mold heating with NOGRID points
NOGRID points can compute and display how the heat is transferred either through heat conduction, heat radiation or by convection via fluid flow. These heat transfer mechanisms can also be fully coupled within a single simulation. In the example on the left, you can see an animation of the temperature distribution as the mold heats up through cyclic loading of a glass gob. This model provides a better understanding of the temperature distribution inside the mold, depending on all relevant process parameters in the glass container forming process. This helps to improve your design regarding efficiency and costs.
NOGRID points is ideally suited for the design of container forming molds. It enables precise prediction of thermal homogenizing as well as heating and cooling rates. By visualizing temperature distributions and heat fluxes within the molds, NOGRID points provides valuable insights into the process. Additionally, it delivers integral quantities that can be used to analyze heat transport efficiency.
Capabilities of NOGRID points CFD software
NOGRID combines powerful capabilities for handling meshless multi-phase flows and allows the simulation of any conceivable geometry and operating mode, such as
- fully 3D computation solving the complete Navier-Stokes equations
- freely definable material properties by equations or curves
- large geometries with small gaps or cutouts and
- variable number of fluids and solids with different material properties
Why choose Nogrid?
NOGRID provides professional CFD software for the simulation of fluid flow, heat and mass transfer, and chemical reactions. Its efficient modelling workflow helps engineers analyse flow behaviour, evaluate designs and make informed decisions without creating a conventional volume mesh.
Faster model preparation
With NOGRID, only the geometry boundary needs to be meshed. The finite points inside the fluid domain are generated automatically according to user-defined settings, both at the start of the simulation and during the calculation.
This approach reduces preprocessing effort and makes it easier to prepare complex geometries and cavities for simulation.
Efficient CFD workflow
The modelling process follows four straightforward steps:
Build the geometry. Mesh the boundary. Define the simulation. Start the calculation.
NOGRID is designed to provide short computation times, including for applications involving complex cavities. Engineers can use the resulting data to examine flow distribution and other relevant flow characteristics.
Better insight into fluid-flow processes
CFD solves the fundamental equations governing fluid flow. NOGRID software enables engineers to predict and analyse the behaviour of fluids and related physical processes before or alongside physical testing.
The simulation results can support:
- evaluation and comparison of design alternatives
- optimisation of construction and operating parameters
- improved planning reliability
- reduction of development time and testing effort
- faster progression from design to market or operation
