7 Challenges CFD Modelling Software Can Solve

Home » Blog » 7 Challenges CFD Modelling Software Can Solve

Computational fluid dynamics (CFD) is an essential tool for the analysis of complex industrial systems. With advances in CFD modelling software, complex systems such as separation systems, pipeline component interferences, and heat exchangers, yield a close estimate of the projected flow properties. Advances such as the cloud has made CFD modelling software more accessible and affordable than ever before, and in this article we explore its role in solving 7 common simulation engineering challenges.

CFD Modelling Software: Overcoming Common Challenges

The report discusses the many common challenges faced by CFD engineers on a day-to-day basis. Here, we've selected seven challenges and identified how CFD modelling software can provide a suitable response and solution.

1. Writing and Debugging Complex Numerical Algorithms

CFD modelling software offers inbuilt models to help engineers save their precious time that would otherwise need to be spent writing and debugging complex numerical algorithms. Moreover, with the availability of inbuilt models, engineers do not need to hire expert workforce or purchase expensive workstations to create  or test different models.

2. Uncertainty of Result Accuracy

Since CFD modelling software tools have already been tested thoroughly by experts in the field, most simulation tools are incredibly accurate and help to provide engineers with an assurance of valid results.

3. Presenting Complex Data To a Non-Technical Audience

It is not always easy to visually display results, especially when engineers have to present their findings to an audience that may not be as technical as they are. Most CFD modelling software tools come with post-processing software to provide the engineer with a visually appealing display of simulation results. Simulation tools that provide effective displays of results using colours or contours can also assist in presenting complex data to a non –technical audience.

4. Difficulty Observing the Effect of Different Parameters

Graphical User Interfaces (GUIs) help engineers easily complete and understand the what-if analysis, saving them time and simplifying what would otherwise be a long and daunting task. Simulation tools have an integrated GUI that can be used to easily vary the parameters (or a combination of the parameters) helping engineers to observe the effect of different parameters.

5. Difficulty Determining How to Apply the Fluid Flow Equations in Specific Scenarios

Field-specific CFD modelling software tools are built by engineers specialized in the respective fields who have in-depth experience dealing with the field-specific problems. CFD engineers can greatly benefit from simulation models like these, as they eliminate the time and effort that would otherwise be spent determining how to apply the fluid flow equations in various specific scenarios.

6. Rewriting Computer Algorithms For Different Flow Types

Different flow conditions can be daunting, as they often require computer algorithms to be re-written several times to account for all flow types when testing a prototype. A number of simulation tools come with the ability to model the flow for different flow conditions such as single-phase flow, multi-phase flow or non-Newtonian flow. This eliminates the effort to rewrite the computer algorithm for various kinds of flows, saving engineers a lot of time and frustration.

7. Estimating Design Parameters 

Before developing customized simulation algorithms for problem-specific needs, it is beneficial for engineers to get a rough estimate of the design parameters. Simulation tools are a great way for them to gain this rough estimate before spending time and money on designs.

CFD modelling software tools are helpful in eliminating many of the challenges that CFD engineers face on a day-to -day basis. These tools have several built-in predefined geometric models that help engineers better understand project variables such as turbulent flow with different boundary and initial conditions. Simply put, CFD modelling software aims to save engineers time and money while providing them with informative data.
