Interests
Followings are the key research interests of mine and are not limited with mainly in automotive and agricultural engineering:
2.1 Computer Aided Technologies (CAx), modeling, simulation & analysis
- Implicit and explicit analysis.
- Multidisciplinary exposure;
- Composite simulation;
- Dynamics of processes;
- Structural analysis;
- Multi body dynamics - MBD;
- Computational fluid dynamics - CFD;
2.2 Hardware to obtain above results
Hardware & Software
It would be impossible to imagine anything without possession of necessary hardware and software tools to allow one to see the beauty of the interests of mine along with its methods. Availability of:
Hardware tools such as:
- Clusters (in terms of Raspberry Pi);
- Parallel computing with Multi GPU nodes, case of blades;
- Multi GPU nodes: case of chassis;
- High performance computing (HPC);
- Nodes (sample below has 120 CPU nodes);
- Computer workstations;
2.3 Software packages/modules depending on the nature of the problems
Problems to be solved normally come from variety of backgrounds: structural analysis in architecture, structural engineering, mechanical engineering etc., molecular analysis as in bioengineering, chemical engineering, pharmacy, etc., dynamic analysis as in racing, fatigue analysis to test the longevity of the structures or life cycle count etc. Some of them are license based whereas other are GNu or free software packages which might involve some level of licensing depending on hwo to use them, personal, education, or industrial.
Software tools like the below have those problems defined in their website or are also taught in colleges as part of the curricula:
- ANSYS - linear and non-liner structural simulation with capability to expand towards CFD problems as well;
- Comsol - multi physics analysis tool;
- LSDyna;
- Altair Hyperworks;
- PALABOS - Parallel Lattice Boltzman Solver for fluid dynamics.;
- etc.
2.4 Scientific background of the problems
Everysince we start studying math classes at school and progress towards concepts such as log, calculus, series, integrals etc, we start questioning the reson for those complex theories and especially their applications.
With the development of software and hardware tools, those scientific backgrounds now need more attention and running SW and HW became a matter of seconds depending on the type of the problem we are addressing.
That in its turn requiring the development of newer and newer theories, pushing the boundaries of science to implement contemporary solutions as in the past, becuase of lacking of technologies those were left open. Hence we hear and read more about following theories.
The picture below can be used to determine which kind of CFD mechanism/application can be chosen depending on the scale of interest, interactions, complexity, number of equation to be solved, and computtion power on hands.
- Lattice Boltzmann Method (LBM) problems can be solved with PALABOS mentioend above
Methods
In order to deal with interests, once has to understand following concepts behind the job for accomplishing which are the core of their realization:
- Finite element modelling or analysis (FEM, FEA) can be used in structural analysis. The elements below can be referenced for accuracy and robustness of the calculations: more nodes - more robustness, quadrilaterals preferred to triangles to get better accuracy as triangles have internal friction to the loads in terms of 2D or planar analysis. For 3D though, it can create the complexity while working with meshes.
