If you want to perform a thermal analysis of drilling - focusing on heat generation and transport - by using simulation our meshless CFD software NOGRID points is a great choice. Based on the geometric model which can either be imported from your CAD system or created using our CAD preprocessor COMPASS, you can quickly generate a computational model of the specific geometry. Compared to mesh-based methods, this approach significantly reduces setup time and allows you to evaluate the thermal characteristics in advance.

NOGRID points shows how the heat is transferred either through heat conduction, heat radiation or convection via fluid flow. You can couple also all kinds of heat transfer mechanisms.

In the example below you can see a drilling process where two different materials - the metal drill bit and the wooden board - transfer the heat. A heat source term is applied at the interface to represent the heat generated by friction between the metal driller and the wood. This model demonstrates how two different materials can be used in a simulation, with the coupled temperature fields computed in both materials based on either a heat source at the boundary or a boundary condition.

NOGRID points can perfectly be used for designing and problem solving of heat transfer cases. It enables accurate prediction of the temperature front as well as cooling and heating rates. NOGRID points helps to understand the flow by visualization of the mass, momentum, and heat transfer of single and multiple phases. You receive integral quantities which you can use to analyze the heat exchange efficiency.

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
