NAFEMS Americas and Digital Engineering (DE) teamed up (once again) to present CAASE, the (now Virtual) Conference on Advancing Analysis & Simulation in Engineering, on June 16-18, 2020!

CAASE20 brought together the leading visionaries, developers, and practitioners of CAE-related technologies in an open forum, unlike any other, to share experiences, discuss relevant trends, discover common themes, and explore future issues, including:
-What is the future for engineering analysis and simulation?
-Where will it lead us in the next decade?
-How can designers and engineers realize its full potential?
What are the business, technological, and human enablers that will take past successful developments to new levels in the next ten years?

Resource Abstract

Today, a large number of simulation programs are used in the automotive development process. To engineer a single component multiple tools, like in FEM FE Simulations (Abaqus Explicit & Abaqus Standard or LS-Dyna), CFD (XFLOW), Metal forming (DYNAFORM) and others are needed. It is therefore not unusual for one component to be modelled in several different codes. Each of these programs requires the basic model input code in its specific program format. The physics of a component are nevertheless unique. Transferring one simulation model completely and automatically from one program to another is not working very well, especially for complex models. One reason for this is the software-dependent implementation of physical problems. The same physics (for example welding spots) are modelled differently for different loadcases. The metalanguage “SMILE” (Unified Simulation ModellIng LanguagE) is designed to solve this problem. The approach is, to document all primary and secondary information of a component in a common format, in order to build a database, that can be used to create an inputdeck automatically for any simulation software or discipline. This works due to a strict separation of geometry and physical properties. An important point for the conversion of an independent modeling language is the renunciation of explicit modelling of the materials. The material in SMILE is assigned by a name reference and must be available in a material database. The basic syntactic requirements of the various simulation tools can be stored and accessed in databases ( “democratisation of simulation”). This approach offers a good basis to realize an automated simulation model generation for any software. A "translator" must be provided for each simulation software. In this presentation the basic idea and features of the language will be presented. Also some examples, defined in SMILE and simulated in Abaqus and LS-Dyna will be shown.
