Beginner in CFD journey has the first question in mind “How do I start learning CFD ?”  Because of the depth of subject and ocean of knowledge available online, there is high probability of getting lost in the learning journey and in many cases getting demotivated from learning CFD itself. This question is asked by many, so I thought of laying out the learning path for CFD beginners. This guide gives a head-start to beginners about what to learn, what to focus on and most importantly from where to learn.

LearnCAx joined Massive Online Open Course (MOOC) on 23rd April 2015. In just 1 month, with 1786 course subscription total 2,57,334 minutes of learning is done by students across the globe. By distributing course worth 0.7 million USD for FREE, LearnCAx platform is marching towards becoming biggest MOOC platform for CFD education.

Computational Fluid Dynamics (CFD) is always been looked at as a complex technology to learn. There are many platforms available to acquire knowledge of subject fundamentals like fluid mechanics, heat transfer and CFD basics, but when it comes to acquiring required software skill sets, there are very few effective platforms.

For solution of any computational fluid dynamics problem, initial and boundary conditions needs to be specified. Boundary conditions are essential component of a mathematical model. They direct the motion of flow which leads to a unique solution. In ANSYS FLUENT (or in general in any CFD software), we are familiar with standard boundary conditions such as inlet, outlet, wall, symmetry etc. These types are of boundary conditions are frequently used. But there are certain applications which require custom boundary conditions which are bit different from these standard boundary conditions. This blog will explain the use of one such “special” boundary condition called “Recirculation Boundary Condition”. This is specific to ANSYS FLUENT solver and is used for specific set of devices/problems.

Many of the advance ANSYS FLUENT users write UDF (User Defined Function) to ask ANSYS FLUENT to do some special jobs. These UDFs are very popular in ANSYS FLUENT user community. Most of the UDFs that we create are programmed for serial mode of ANSYS FLUENT since it only involves basic C program coding with required marcos. However, to utilize the power of parallel processing, we need to convert the serial UDF into parallel UDF. Read this blog for a step by step process to convert serial UDF to parallel UDF.

As a computational geometry developer I have worked on several meshing software development projects. Every time mesh quality has become focal point. As matter of fact this becomes conflicting topic between the various teams due to the difference of opinion in engineering community.
