The paper introduces a novel approach to the implementation which handles a general formulation composed of user-defined expressions and interaction-laws covering an extensive range of particle-based methods. As a result, Nauticle has three distinct levels for users and developers. At the top level, the Symbolic Form Language (SFL) of Nauticle facilitates the formulation of user-defined numerical models in text-based configuration files. The SFL can be intuitively extended at the intermediate level with new particle methods without tedious re-coding or even the knowledge of the bottom level. The paper presents the structure of the underlying general algorithm; then the top two levels are discussed in detail and illustrated by simple application examples. Finally, the efficiency of the code is also tested through a performance benchmark.}, year = {2020}, eissn = {1879-2944} } @article{MTMT:30393877, title = {Heterogeneity effects in power grid network models}, url = {https://m2.mtmt.hu/api/publication/30393877}, author = {Ódor, Géza and Hartmann, Bálint}, doi = {10.1103/PhysRevE.98.022305}, journal-iso = {PHYSICAL REVIEW E}, journal = {PHYSICAL REVIEW E: COVERING STATISTICAL NONLINEAR BIOLOGICAL AND SOFT MATTER PHYSICS (2016-)}, volume = {98}, unique-id = {30393877}, issn = {2470-0045}, year = {2018}, eissn = {2470-0053}, orcid-numbers = {Ódor, Géza/0000-0001-9259-5352} } @inproceedings{MTMT:2699172, title = {Flow Structure Detection with Smoothed Particle Hydrodynamics}, url = {https://m2.mtmt.hu/api/publication/2699172}, author = {Havasi-Tóth, Balázs and Szabó, K.

We demonstrate the use of the Delta criterion for the detection of instantaneous Eulerian flow structures. The standard calculation of the velocity gradient tensor (VGT) results too noisy gradient field. We propose a correction method based on the idea of XSPH that yields a much smoother VGT field, enabling significantly more accurate structure detection. We also demonstrate on test cases the process in which the instantaneous Eulerian tools are used to locate Lagrangian coherent flow structures.}, year = {2014}, pages = {208-215}, orcid-numbers = {Szabó, K.
