Lecture 4 Getting Started with ABAQUS ABAQUS : a suite of powerful engineering simulation programs, based on the finite element method 1. Can solve problems ranging from relatively simple linear analyses to the most challenging nonlinear simulations. 2. Extensive library of elements that can model virtually any geometry. 3. Extensive list of material models that can simulate the behavior of most typical engineering materials. 4. Can simulate problems as heat transfer, mass diffusion, thermal management of electrical components (coupled thermal-electrical analyses), acoustics, soil mechanics (coupled pore fluid-stress analyses), piezoelectric analysis, and fluid dynamics. ABAQUS Products ABAQUS Documentation provides everything you need in learning ABAQUS The best way to learn ABAQUS is to follow the examples There are many types of example problems You may also start from Benchmark Examples that are simpler. Let’s start from the geometrically nonlinear analysis of a cantilever beam For this example, there are a lot of input files according to various element types Click on the name to obtain the input file Copy this file to a folder which you want to run ABAQUS Use ABAQUS Keyword Reference Manual to understand the meaning of each command Or you can download this file by the following procedure: 1. Run the ABAQUS command window (from the program list) 2. Change the working directory to the one which you wish to run The input file name can be found in the ABAQUS manual 3. Type this command: abaqus fetch job=input file name Now your folder should have this file: We can then run this
