Hi All, Recently I wanted to investigate the use of OpenFOAM for CFD calculations for a model built in CAESES and perform an optimization at a later stage. Although the OpenFOAM is a C++ library meant to be run in Linux systems, I wanted to test the configuration on my Windows pc and I found this compiled OpenFOAM 2.3 version available. After installing the software as instructed I had to change a little bit the configuration of the software connector in CAESES. Basically, I called the mintty.exe terminal application and run a modified version of the Allrun.sh shell script, as demonstrated at the ahmed body sample. You can find attached a picture of the LocalApplication and its arguments, the modified shell script Allrun.sh and the modified project file of the Ahmed Body sample provided with CAESES installation. Please notice that I have configured the OpenFOAM calculation to run on a single processor and deactivated any parallel computing, because of my restricted resources, but you could easily restore that back. I had also to change some points in the RunFunctions file located in /opt/OpenFOAM/OpenFOAM-2.3.x/bin/tools and you can find attached this new file too. If you are interested in learning how to manipulate OpenFOAM or try some simple simulations on your windows machine, you can give it a try. Cheers, Ilias. ahmedbody.fdbc Allrun.zip
Hi together, Please note that CAESES can be utilized as an OpenFOAM GUI (Graphical User Interface). There are free academic versions of the CAESES pro edition for students and PhD students as well as trial licenses with flexible time frames. There are also special editions for small companies, start-ups and freelancers. Compared to other tools in the market, CAESES is good at automation, i.e. if you already have an existing OpenFOAM setup and you want to analyze design variants of your product, then CAESES might be a perfect choice. Especially, if geometry variation plays a major role. In contrast to that, a tool such as HELYX-OS might be a better choice e.g. if you would like to set up an OpenFOAM case from scratch. Here are some CAESES-specific offers: Conveniently configure and manipulate template files (e.g. controlDict or any other ASCII file) in the GUIChange your geometry design and trigger OpenFOAM with a single mouse-click for analysis (i.e. streamline your design process / automation)Use your individual result values such as pressure loss or homogeneity for an objective function in design studies and shape optimizationsPostprocess your simulation data (streamlines, contour plots etc) Here is a video that shows some of the features in CAESES.
