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

fully 3D computation solving the complete Navier-Stokes equations
easy and intuitive setup for thermal analysis 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
