The main objective of this project is to make HPC equipment available to the Cepid-CeMEAI researchers and other researchers in the State of São Paulo with international service standards. The Euler Cluster today in operation was awarded to Cepid-CeMEAI and initially installed in 2015, with 4160 Logical Cores, 175 TB NFS, 175 TB of high-performance All-in-One Storage mounted with INFINIBAN…
The focus of this proposal is the transfer of mathematical knowledge to other areas of science, technology and industry, through a structured research center specially tailored for this purpose. All mathematical knowledge is ultimately applicable, if not directly, through other areas of knowledge. In some areas the application of mathematics is almost immediate. However, the practical imp…
This project is concerned with the development of a numerical method for solving biaxial nematic liquid crystals subject to a strong magnetic field. The director is fixed by this field and is described by two angles. The first task is not difficult but extremely tedious: to derive the components of the stress tensor. A code will be constructed/extended from an existing code for uniaxial n…
Before explaining the work plan, it is worth describing the concepts that unify it. Throughout, the basic starting point is the mathematical modelling of complex multiphysical phenomena occurring in industrial processes or in nature, with a view to providing a quantitative description of mechanisms or operation. This is done through the formulation of systems of partial differential equat…

Currently, there are no concrete studies of the textual description of electronic invoices for the extraction of relevant information to be used, for example, in the detection of product overprices and overpricing of public contracts. In general, electronic invoices contain insufficient and unstructured information causing great difficulty in determining products and services. In order to…
This project is a proof-of-concept of a novel aortic valve for the human heart. It involves mathematical modelling spiral and pulsatile blood flow from the left ventricle into and through an artificial heart valve. The valve has three leaflets (or flaps) which open and close in accordance with systole and diastole. These large (elastic) deflections, driven by the pressure gradient of the …

In this doctoral project it is proposed the development of an axisymmetric code for the solution of complex fluid flows, i.e. materials combining viscosity, elasticity and plasticity effects. The applications of interest are flows with free surfaces and with topological changes, as in the case of the impact of droplets in different types of surface (rigid or fluid layer) and the coalescen…
This project proposes the study of numerical methods for the solution of incompressible and non-Newtonian fluid flows, with emphasis on the effects of surface tension. Mathematical modeling involves the Navier-Stokes equations and a system of equations that define the contribution of the non-Newtonian tensor. In addition, the modeling will use the conditions of free surface contour consid…

In this project, we propose to develop and test a new computational platform for droplet dynamics of complex fluids. In particular, we are interested in problems such as the spreading of a droplet, and the coalescence or collision between droplets. Complex fluid models will be considered, such as yield-stress or elastoviscoplastic fluids. These numerical simulations will be used alongside…
In this project, we propose to investigate some recent methodologies to treat high elasticity fluid flows. In particular, we are interested dealing with viscoelastic free surface flows considering the effects of surface tension, as for example, the die-swell extrusion and injection moulding problems. The constitutive equations used to model the rheological behavior of the fluids will be r…
The main topic of research addresses the occurrence of macrosegregation in ingot casting, a phenomena that can actuate to depletion of the product's final quality. Such formation can be described as an severe variation on macroscopic scale of chemical species that compose the alloy, and the prediction of such occurrences via computational simulations has yet to be improved. Therefore, thi…
In this project, we will investigate a new formulation for solving viscoelastic free surface flows. This methodology is mathematically rooted in a dyadic decomposition of the conformation tensor which results in an efficient method for dealing with stress singularities. The research is focused on benchmark flows in the presence of free surface boundary conditions, e.g. stick-slip and die-…
