If you want to perform a thermal analysis of cooling a human head NOGRID points is an excellent choice. Simulating the cooling process of the human head is crucial for optimizing thermal management in medical and safety-related applications. 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 the specific geometry. Compared to mesh-based methods, this approach significantly reduces setup time and allows you to evaluate the thermal behavior in advance.

Heat transfer mechanisms

The heat can be transferred either by heat conduction, radiation, and/or convection via fluid flow. All types of heat transfer mechanisms can also be coupled within the simulation. In the example shown on the left, the human head is cooled using appropriate boundary conditions (without directly computing external airflow), and the head is modeled as a homogeneous body with internal heat sources. In this case, only heat conduction is considered. The results show that the temperature decreases first in the ears and the nose.

Why choose NOGRID for thermal simulations

NOGRID points is highly effective for designing and solving heat transfer problems. It enables precise prediction of temperature front propagation as well as cooling and heating rates. NOGRID points supports a deeper understanding of flow behavior by visualizing mass, momentum, and heat transfer in both single-phase and multiphase systems. In addition, it provides integral quantities that can be used to evaluate and optimize the efficiency of heat exchange processes.

Capabilities of NOGRID points software

NOGRID combines the ability to handle free surface flows and moving parts within the domain, allowing for the simulation of any geometry and operating mode, such as:

computation is in full 3D solving complete Navier-Stokes-Equations
easy and intuitive setup for thermal analysis cases
free 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

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.

Easy and fast modelling: Build geometry, mesh boundary, setup the case and start computation

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.
