ABSTRACT

Last October marked the tenth anniversary of the appearance of the first paper [1] describing a vision of how to address a major problem in Computer Aided Engineering (CAE).  The motivation was as follows:  Designs are encapsulated in Computer Aided Design (CAD) systems. Simulation is performed in Finite Element Analysis (FEA) programs.  FEA requires the conversions of CAD descriptions to analysis-suitable formats from which finite element meshes can be developed.  The conversion process involves many steps, is tedious and labor intensive, and is the major bottleneck in the engineering design-through-analysis process, accounting for more than 80% of overall analysis time, which remains an enormous impediment to the efficiency of the overall engineering product development cycle. 

The approach taken in [1] was given the name Isogeometric Analysis.  Since its inception it has become a focus of research within both the fields of FEA and CAD and is rapidly becoming a mainstream analysis methodology and a new paradigm for geometric design [2].  The key concept utilized in the technical approach is the development of a new foundation for FEA, based on rich geometric descriptions originating in CAD, resulting in a single geometric model that serves as a basis for both design and analysis. 

In this short course I will introduce Isogeometric Analysis, describe some of the basic tools and methods, identify a few areas of current intense activity, and areas where problems remain open, representing opportunities for future research [3].

To face the major causes of death in developed countries, the event will bring together multidisciplinary participants and encourages new connections. 

Within the activities of the UT Austin | Portugal CoLab Program in Advanced Computing, the Workshop will take place at the Lisbon Academy of Sciences  on November 13-15, 2017. 

The Workshop follows a series of events organized in the previous years devoted to this multidisciplinary research field which demands different expertise and an effective national and international collaboration between mathematicians, computational scientists, bioengineers and medical doctors to address complex biomedical problems.

Its main goal is to bring together doctoral candidates, postdoctoral researchers and graduates interested in Computational Medicine and Biomathematics, giving them the opportunity to make scientific interactions and new connections with established experts in the different topics covered by this event. Through this workshop, it is also expected to foster the collaboration between members of the different areas of the UT Austin | Portugal community.

Poster presentations are welcome.

Free entry, registration required.
