Ansys Tips

Fig 1: Project Schematic With the release of Mechanical 19.2, substructuring is now available for Modal & Rigid Dynamics without scripting. That just made my  earlier post on CMS outdated! Note that there is still a key limitation where Generation and Expansion Pass must be performed on your local machine. To get ahead of the game a bit, here is a way to do Harmonic Analysis extending on previous work . (Please go through that before this post). Some points of note: The method of merging the CMS and non-CMS models together into System C is the same. All files related to the superelement has to be copied over to the solver file directory as before. Modal analysis need not be performed first as the example here uses  Full Method  instead of Modal Superposition for simplicity.  The script expands the responses the same way as Modal Analysis does so the script will look familiar.

Figure 1: Colab by Google Ansys has  ACT extension where users can do some customization using a popular programming language called Python. The barriers to learning Python is now much lower but I'm still stumped by Object Oriented Programming. Hopefully this post would be useful to those who fit the following demographics: Knows simple programming concepts like loops and functions Understand some Calculus Side Notes on Ansys ACT Before You Begin Ansys uses  IronPython 2.7  which is an implementation in the .NET framework. Unfortunately, as I understand it, some libraries such as NumPy are difficult to install . Colabs Colaboratory Research by Google (Fig 1) is a neat tool. All you need is a free Google account and you can execute Python scripts in the browser. No installation required! It has Jupyter notebook running in the background and allows both Python 2 or Python 3. While NumPy and Matplotlib is already installed by default, you could install other librarie
