If you want to make a thermal analysis for the cyclic heating of molds for container forming processes by using simulation then our meshless CFD software NOGRID points is a great choice. Based on the geometrical model which can either be imported from your CAD or created with our CAD pre-processor COMPASS you can generate a computer model of a specific geometry in a very short time (compared to mesh-based methods) and see its thermal characteristics in advance.

Periodic heat loads or cyclic heating of molds are very common in industrial environments. Starting with a cold solid mold, the temperature increases over time with the period of the process until a steady-state temperature distribution is established within the mold. At that stage only the temperature at boundaries where the heat load is applied will change with the given period.

NOGRID points can compute and display how the heat is transferred either by heat conduction, heat radiation or by convection by means the flow of a fluid. You can couple all kinds of heat transfer mechanisms as well. In the example on the left side you can see an animation of the temperature distribution while the mold is heating up by cyclic loading of a glass gob. This model gives you a better understanding of the temperature distribution inside the mold depending on all process parameters within the glass container forming process. This helps to improve your design regarding efficiency and costs.

NOGRID points can perfectly be used for designing of container forming molds. The thermal homogenizing and the cooling/heating rate can be predicted. NOGRID points helps to understand the process by visualization of the temperatures and the heat fluxes inside the molds. You can receive integral quantities which you can use to analyze the heat transport efficiency.

NOGRID unites abilities to handle meshless multi-phase flows and allows the simulation of any conceivable geometry and operation modes such as

  • computation is in full 3D solving complete Navier-Stokes-Equations
  • free 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

Nogrid's strengths

Particular strengths of NOGRID's fluid flow CFD software are the rapid preprocessing (no fluid grid needs to be generated, only the boundary mesh, inner finite points are generated automatically depending on User setting initially and during computation), and the outstandingly short computation time even for complicated cavities.
As you can see in the image below, the boundary of the geometry still requires a mesh to allow the interior finite points to detect the boundary. The boundary must therefore be meshed and the finite points inside are automatically generated during the simulation controlled by User specifications.

What is CFD from NOGRID?


CFD solves the fundamental equations that define the fluid flow process. With CFD software from NOGRID every engineer makes better decisions by predicting, analyzing and controlling fluid flow, heat and mass transfer or chemical reaction. By using NOGRID software for flow modeling you receive information on essential flow characteristics as for example flow distribution. Using it additional to testing and experimentation NOGRID software helps to improve the evaluation of your design – resulting in better construction and operation parameters, increasing planning security and money savings due to faster time to the marketplace for your product or process.
