4. Open-Source CFD Simulation Software Package

Open-source software is Distributed under an openly accessible software license Policy that permits end users to
– Examine, Modify the original Source code
– Freely Share and Distribute the CFD Software Source Code for Personal Use (Both Commercial & Non-Commercial)
– Customize to improve the Open Source software program
Such a Flexible Licensing Policy Structure generally ensure that the open source software application pack is Freely distributed Openly in the public domain and remains free of High cost.
At the same time, open public access of the software source code helps to retain a wide Pool of User and volunteer developer community base.
In the case of open source CFD Fluid Dynamics Software application solution packages such as OpenFoam, they have Steeper learning curve for the average user, but it can save you a lot of money and licensing cost, especially if you’re not a student or in academia where using of Free Academic account license or Trial software (which can be downloaded from the website) is quite common


OpenFoam CFD Software

One of the industry Leading, most popular and widely used general purpose open-source CFD software solution is known as OpenFOAM. While the official OpenFOAM software version release is Regularly updated by the OpenFOAM Foundation, a Small Number Of splinter cell groups have broken off with unique code variations in order to commercialize some aspect of their code additions to the main Source code, typically through CFD Simulation consulting service.
Some of the major flavors of This Free Open Foam Software solution includes
– blueCFD-core
– openFOAM+
– SU2 (Stanford University)
– Lattice-Boltzmann solver Palabos



Advantages of Open Source CFD Software

The lead arguments for the choosing of open-source CFD software solution are the following.
1. Open Source License Policy on Software Distribution 
An open sourced Software distribution model means that it is freely licensed without any cost restrictions, making it increasingly cost-effective as your Simulation usage demand Rises over time.


2. Long Term Sustainable Reliability & Maintenance of Source Code 
If a Software code is widely distributed internationally, it will tend to be comparatively more Robust and accurate as a natural result of the CFD Source code being Closely scrutinized and improved by a large public Pool of Passionated and Experienced Software developers all interested to ensure that the source code performs well without any bug.


3. Customization & Reconfigurability of Source Code by End Users 
In addition, if an end user has the prior Job experience in Technical coding, software development skill and Understanding of the specific Industrial research application the CFD Software is being used for, they can have the Full freedom to add useful functionality through additional Software coding.


Disadvantages of Open Source CFD Software

On the other hand, one of the major arguments against open-source is
1. Limited user technical support Services & Resources for End users, resulting in difficulty in attempting to book a ticket support
2. A naturally increased cost of long term Operating Cost & Ownership Cost attributed to poor overall usability, which results in longer Classroom training hours required to be Invested on watching Tutorial Video content resources on online Training site due to a Steeper Software learning curve
3. Lack of specialized simulation modeling capabilities for unique physics events
4. A requirement for additional software modules transfer add-on from other 3rd party Developer company, such as pre-processing and post-processor modules, which Creates a separated Layer of Dependency in the Source Code.

5. Open Source Wrappers

In order to make open-source CFD Software more intuitive to the average user and user-friendly to new users, CFD Software developers have created Embedded middleware in the form of wrapped codes such as Open-FOAM which is more user-friendly.
It has a Graphically Driven GUI Simulation view environment with a GUI layout which is bundled with additional processing software modules, such as pre-processing Solvers and post-processors.
Examples are Visual-CFD, HELYX, and simFlow.


The Industry Trend of Online Cloud-Based CFD Simulation

A recent interesting evolution on this software development concept in the Engineering Consulting industry now is that of online cloud-based High-Performance Computing (HPC) CFD simulation methods which Fully relies on a web browser to perform the actual customized CAE simulation solving process.
Two Examples of such Highly dynamic and scalable HPC Cloud-based CFD simulation Solutions include
1. Siemens Simcenter STAR CCM+ Power on Demand
2. SimScale


1. Advantages of Wapper Platforms

The obvious Advantages of adopting a wrapper platform is that they can offer some of the immediate convenience of a Full-fledge commercial CFD software platform with a much Cheaper Affordable price point.


2. Disadvantages of Wapper Platforms

On the downside, the arguments against wrapper platforms are that they are unable to overcome some of the inherent limitations of open-source Software, such as limited & non-comprehensive user technical Tech support services and lack of specialized solving capabilities needed for niche high Test simulation applications.


Dependency on 3rd Party Software Modules
Wrappers essentially serve as a middleware which does offer the end user the Full convenience of accessing just a single Integrated graphical user interface but suffers from the fact that the platform setup involves an additional level of Dependency and undesired separation between the Software user and the Actual execution Source code File.
Both of which places an undesired increase in computation demand on the precious CPU processors and computational resources
Adding another level of add-on software code increases the probability for software bugs to occur, which volunteer developers may be slow to rectify due to the fact that it is Open source and not commercial.
