Visualisation of flow calculations

The major providers of flow simulation software, such as Ansys Fluent, Ansys CFX, Simcenter Star CCM+, FLOW-3D® oder Simerics MP+ each offer in-program options for evaluating and visualising simulation results.

In our company, the engineers also use different software for flow calculations, depending on the application. For the visualisation of the results, however, we mostly use only 1 product – and this has been the case for many years: FieldView.

What we appreciate about FieldView is the ease of use, the high degree of automation when comparing calculation results of geometry and case variants, the enormous number of interfaces to commercial and non-commercial flow simulation programmes and the handling of large and very large amounts of data in client-server mode.

An example: The first two pictures show two variants of the flow through an aneurysm in a blood vessel. Differences in pressure are difficult to see. If you use the “Dataset Comparison” feature to compare the pressure in image 2 with the pressure in image 1, the existing pressure differences can be elegantly visualised (red: higher pressure, grey: identical pressure, blue: lower pressure).

Visualisation with FieldView

The automation of repetitive tasks is also very conveniently solved by restart files and – if required – the script language FVX. Visualisations can thus actually be created with a click of the mouse.

Thanks to comprehensive downward compatibility, result files and self programmed routines can still be read into the latest FieldView version without any problems, even after many years. And the development of FieldView continues: one focus is on processing the enormous amounts of data that arise due to the rapidly growing hardware performance in three-dimensional flow calculations – Big data!

Thank you, Ibrahim Başhoruz!

From September 2020 to January 2021, Ibrahim Başhoruz was part of the CFD Consultants team and worked on a specialist internship thesis in our Rottenburg office as part of his Bachelor’s degree in “Mechanical Engineering with Business Administration” at the Technical University of Kaiserslautern.

Ibrahim Başhoruz was involved in various projects in our company, for example in the areas of automobile racing, wind tunnel, flow around buildings or the flow around wing profiles and worked very well into the operation of software tools for numerical flow simulations (CAD data preparation and pre-processing with Rhino and Pointwise, numerical simulation with Ansys Fluent, post-processing with FieldView).

During the lecture Fluid Mechanics III – CFD and the exercise in CFD, which our managing director Dr. Volker Kassera held this year purely virtually as a video conference with ZOOM for the students of the Chair of Fluid Mechanics and Fluid Machinery (SAM) at the Technical University of Kaiserlautern, he was always happy to assist.

Many thanks, dear Ibo! That was really good, including the baklava 🙂 !

We wish you all the best for your subsequent Master’s degree at the University of Kaiserslautern!

Project PRESTIGE: In-situ visualization of flow processes in very large CFD calculation models

As part of the aviation research programme of the Federal Ministry of Economics and Energy (BMWi), the joint project PRESTIGE was launched in 2018. This project brings together partners from academic research and industry and is dedicated to the further development and validation of simulation methods to improve the interdisciplinary understanding of engine systems.
One goal of the project (…)

“Freezing” instruments due to new acoustics?

Anyone who has ever attended a concert – whether Philharmonic or rock concert – has experienced that such a concert is a pleasure for (almost) all our senses. For an unforgettable experience you want, no, you have to feel, see and above all hear the music.

This is especially true for
