If you want to make a thermal analysis of concrete hydration 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 preprocessor 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.

NOGRID points shows how the heat is transferred either by heat conduction, heat radiation or by convection by means the flow of a fluid. You can couple also all kinds of heat transfer mechanisms. In the example below you can see the temperature evolution during a concrete hydration process. The reaction with water is termed as "hydration". This involves many different reactions, often occurring at the same time. As the reactions proceed, the products of the hydration process gradually bond together the individual sand and gravel particles and other components of the concrete to form a solid mass.

In this simulation we used a time dependent heat source and the temperature evolution is shown in Figure 2. The initial and the ambient temperature were set to 15 °C.

This model can give you a better understanding of the concrete hydration process and helps to improve your design regarding efficiency and costs. If something should be missing for your purposes, please let us know, we can easily implement additional requirements.

NOGRID points can perfectly be used for designing and problem solving for all kinds of thermal processes. The thermal homogenizing, the temperature gradients and the cooling/heating rate can be predicted. 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 fluxes efficiency.

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 simulation software 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.
