Simulation Software for Fluids and SolidsSimulation Cooling Mainboard
If you want to perform a simulation of cooling a mainboard, you can use the CFD software NOGRID points.
Computer-aided thermal analysis is already widely used today, allowing development cycles for heat dissipation and cooling concepts to be significantly shortened. In this study, the airflow used to cool a computer mainboard with several components is simulated. The mainboard is modeled as a thermally conductive solid, enabling it to absorb and release heat. The air flow is a forced flow, such as that generated by fans.
Based on the geometric 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 mesh-based methods) and see its thermal characteristics in advance.
In this study, heat transfer within the solid is modeled solely by conduction, with ideal thermal contact assumed between the air and the solid. In the air, heat can be transferred by conduction, radiation, and convection. Convection refers to heat transport caused by fluid motion. All types of heat transfer mechanisms can also be coupled in the simulation.
In the example shown on the left, the mainboard and its components are cooled by the surrounding air. The components are modeled as homogeneous bodies with internal heat sources. In the solid, only heat conduction is computed. Since both a solid and a fluid are in thermal contact and exchange heat, this configuration is also referred to as a multi-phase flow.
Capabilties of NOGRID points CFD software
NOGRID points is ideally suited for the design and problem solving of heat transfer cases. It enables accurate prediction of temperature front propagation as well as cooling and heating rates. NOGRID points provides valuable insights into flow behavior by visualizing mass, momentum, and heat transfer in both single-phase and multi-phase systems. You receive integral quantities which you can use to analyze the heat exchange efficiency.
NOGRID combines powerful capabilities for handling free-surface flows and moving parts within the computational domain and allows the simulation of any conceivable geometry and operating mode, such as
- fully 3D computation solving complete Navier-Stokes equations
- easy and intuitive setup also for FSI (Fluid-Structure-Interaction) cases
- freely definable material properties by equations or curves
- evaluation of chemical reactions and corresponding heat source terms
- open or closed domains including inflow and outflow areas (non-batch mode)
- moving of parts and flexible thermal contact behaviour
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
