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.

Hello Friends, its being a long time I haven't shared any new information on User Defined Functions (UDFs) available in ANSYS Fluent. Well that may make you think that UDFs are so tough to create, that this person took so long to write his second experience (blog) on UDF! Yeah, it’s funny, but let me tell that this is not the case with me, they (UDFs) are actually so interesting …and huge time & manual effort saver …and productive …and… I can go on and on if I start listing down all the plus points of using UDFs in Fluent. So, long story made short, I was fully enjoying past few months in learning and using this UDF & Scheme programming knowledge to Automate CFD studies in ANSYS Fluent.

The particulate emissions from process industries has received great attention due to the upcoming strict environmental protection agency (EPA) regulations and conservation in recent years. The Electrostatic precipitators (ESP) since its development in 1907 by Frederick G. Cottrell (Professor of chemistry at the University of California, Berkeley) have been the most common, effective and reliable technologies for removal of hazardous emissions like flue gases, acid droplets and fine particles.

The article is about a popular model available in ANSYS FLUENT, the solar load model (SLM). Here we will try to understand the simple overview of SLM and also have a demo video of a test case created using  for setting up the SLM. To understand its significance it would be interesting to understand the physics happening when we say solar loading.

Writing a UDF i.e. a user defined function, has always been a challenging stuff for CFD engineers those have never tried out one, nevertheless has been a matter of interest for all. Hereby we present a short article to demonstrate the significance of writing a UDF in CFD modeling with a simple test case that would help us all to develop an understanding at the introductory level.
