UNCERTAINTY QUANTIFICATION AND STOCHASTIC MODELING

Description:

The rational treatment of uncertainties and their effects in computational mechanics has received increasing attention, particularly in recent years. In many cases and circumstances, loading conditions, material properties, and/or geometry exhibit variabilities of significant importance. Observations and measurements of physical processes, as well as parameters, display random characteristics. Consequently, statistical techniques and probabilistic procedures provide a very useful framework with a rational basis for the analysis of these uncertainties. In addition to uncertainty in model parameters, uncertainty in the models as a whole also plays a very important role in contemporary computational mechanics.

In summary, neither a true model nor the parameters of the model are actually known deterministically. It is because of the presence of these uncertainties that the assumption that finer discretizations lead to greater accuracy becomes mythical. In this context, aspects of model validation and verification are also addressed.

This mini-symposium will discuss computational and conceptual aspects of uncertainty processing.

The main topics of the session include:

  • Uncertainty quantification
  • Stochastic modeling
  • Probabilistic methods in mechanics
  • Dynamics of mechanical systems

COMPUTATIONAL FLUID MECHANICS

Description: 

This session covers works related to the development of numerical or computational techniques, or the application of already established numerical or computational techniques to problems in Fluid Mechanics. These numerical techniques are based on finite elements, finite volumes, finite differences, boundary elements, particle methods, or others for solving boundary value problems, initial value problems, or mixed problems. Additionally, the applications encompass areas such as aeronautics, astrophysics, biology, chemistry, mechanical engineering, biomechanics, process engineering, environmental engineering, hydraulics, meteorology, oceanography, geology, acoustics, and combustion, among others. This variety of applications allows addressing topics such as numerical simulations of: flows at high Reynolds numbers (involving turbulence modeling through different techniques such as DNS, LES, RANS, hybrid RANS/LES, or others); flows at low Reynolds numbers (Stokes flows), multiphase flows, flows including species transport, flows in porous media, or microfluidics. In all cases, the validation of numerical models against analytical, semi-analytical methods, and/or experimental results, their proper calibration, and their application to real cases are also topics of importance in this session.

HIGH PERFORMANCE COMPUTING

Description:

he continuous growth in computer processing capabilities demands adaptation in the way we work to optimally utilize these computational resources. In the last decade, the only argument that has increased processing speed in computers has been parallel computing, whether it’s instruction-level parallelism, data parallelism, thread parallelism, or node parallelism. The complexity of modern computers involving these four forms of parallelism requires programming to efficiently harness these billions of transistors to achieve good performance, efficiency, and scalability. This also leads to proposing optimizations for existing programs as well as new algorithms and data structures for problems in computational mechanics and multiphysics.

This session aims to provide a forum for those working on solving problems in computational mechanics and multiphysics on traditional processors (CPU) or accelerators (GPU/MIC), leveraging all dimensions of parallelism, as well as on clusters of nodes of these processors and dedicated cloud services.

POSTER CONTEST

Description:

As tradition in the congresses organized by AMCA, MECOM 2024 will hold a poster contest for undergraduate students enrolled in bachelor’s and engineering programs, who are not graduates as of the abstract submission deadline. A judging committee, appointed by the Organizing Committee and the Scientific Committee, will select the best works based on criteria of originality and presentation. Only one work per participant will be accepted; however, a student may present on behalf of multiple students and may have tutors, teachers, and researchers of any rank as co-authors. The presentation must be made in person by the student.

To participate in the poster contest, students must follow the same process as any other submission, i.e., through the OCS system, they must submit:

  • An abstract (with the same deadline as the abstract submission) following the instructions on the website.
  • A poster in PDF format (with the same deadline as the full paper submission).

The poster format is free, but it must be A0 size, contain the congress logo, and not exceed 10MB. The names of the participating students must be underlined to differentiate them from the tutors.

Note: Students should not submit a complete paper for the contest. If they do, they must submit it to regular sessions with a different title and depth of research, to be evaluated by the corresponding session directors.
