Dear Colleagues,

The modeling and optimization of processes or products is today one of the most outstanding points for the advancement of today’s society. Numerical modeling and machine learning techniques are undoubtedly among the most powerful methods and techniques for modeling and optimizing processes and products, reducing their cost of design and subsequent manufacturing.

The main aim of this Special Issue on “Numerical Modeling and Machine Learning Techniques” is to present new knowledge and trends using numerical modeling or machine learning techniques for modeling and optimizing processes or products. Numerical modeling techniques of interest in this Special Issue include but are not limited to finite element analysis, the finite volume method, the finite difference method, the boundary element method, discrete element methods, multibody simulation, and computational fluid dynamics. Classification, regression, and optimization algorithms could be considered in developing machine learning or Artificial Intelligence techniques.

Dear Colleagues,

The fight against the COVID pandemic is a call to all fields of scientific research, not only to medical and public security experts. Engineers can contribute to the development or optimization of solutions that would allow us to detect, cure, and contain the spread of this subtle disease.

Ideas and new approaches for the optimization of existing products such as protective masks, assisted breathing devices, diagnostic systems, or medical organizations and procedures have greatly multiplied. A variety of technologies are being brought to the test field for the design and rapid development of new products. Provided that there is a lesson to be learned from the present situation, it is important to take advantage of this large effort and evaluate the potential of these new technologies from the perspective of development speed, time to market, and sustainability.

Original manuscripts exploring practical case studies of innovation, development, and / or optimization of medical or everyday use products, highlighting the aspects related to design choices (green design methods, materials, recyclability, ease of disposal) are invited. Case studies focusing on the description of the new development paradigm are also welcome, considering as significant aspects the proposal of rapid, innovative, and sustainable solutions also at the level of engineering education for sustainability.
