SANMoMa is a traditional meeting that began to be implemented in 2011, promoted by Gabriel Gatica..
The Seminar on Numerical Analysis and Mathematical Modeling (SANMoMa) is a periodic event organized by researchers of the Numerical Analysis of Partial Differential Equations (NA of PDEs) of the universities of Concepción (UdeC), Bío-Bío (UBB) and Católica de la Santísima Concepción (UCSC).
It began in 2011, promoted by the academic Dr. Gabriel N. Gatica of the UdeC and researcher of the Center for Mathematical Modeling (CMM) of the U. of Chile, together with researchers David Mora Herrera and Ricardo Oyarzúa of the UBB. To date, more than 50 international researchers, specialists in PDEs and Mathematical Modeling have presented their work.
“Initially,” said Prof. Gatica, ‘one of the ideas behind this activity was to further motivate the creation of a joint UdeC-UBB-UCSC doctorate in this discipline, which practically already existed in those years thanks to the collaborative work between researchers from the 3 universities and the cross co-direction of graduate theses, but which needed to be made official’.
The also member of the Center for Research in Mathematical Engineering (CI²MA) of the UdeC added that “unfortunately, the project was diluted over time, mainly due to the lack of support and institutional interest and the prioritization of rather political initiatives to the detriment of the academic ones, and even due to the realization, very valid in any case, by some of those involved, that perhaps it was no longer necessary to join efforts. This explains why, in this new version of the seminar, the reality has been assumed and the talks are aimed primarily at undergraduate and graduate students of the UdeC”.
In 2019, Bryan Gómez and Paul Méndez, at that time students of the PhD program in Applied Sciences with mention in Mathematical Engineering at UdeC, began to organize the Student Numerical Analysis and Mathematical Modeling Seminar or SANMoMa-Graduates, conceived as an informal instance of conversation between students of the graduate programs of the Concepción pole of AN of PDEs, whose objective is that students present to their peers, both current challenges and partial or final results of their work, and thus generate a discussion that allows enriching their research.
SANMoMa 2024
After a pause due to extra-academic reasons, at the end of this year, the students of Mathematical Civil Engineering at UdeC -and research assistants of Prof. Gatica- Alonso Bustos Barría and Benjamín Venegas Solís took charge of the organization of SANMoMa-Graduates.
“This seminar seeks to bring the area of numerical analysis closer to both undergraduate and graduate students, through presentations made by researchers and students in the area. In this way, it seeks to generate a space for conversation between the different areas of numerical analysis, where students can learn from those with more experience”, Benjamín said.
The cycle lasted from Wednesday, November 6th to Thursday, December 19th and was structured in two thematic groups of three lectures each:
Mixed Finite Element Methods.
- A conforming and divergence-free approximation for the pseudostress-based formulation of the Stokes problem‘, Dr. Jessika Camaño Valenzuela, UCSC.
- ‘A twofold perturbed saddle point-based fully mixed finite element methos for the coupled Brinkman-Forchheimer/Darcy problem‘, Sergio Carrasco Hidalgo, Monash University (Australia)
- Mixed Finite Element Methods for Fluid Filtration through a Saturated Porous Medium with Heterogeneous Permeability: A Priori and A Posteriori Error Analysis‘, Dr. Sergio Caucao Paillán, UCSC
Discontinuous Galerkin and HDG Methods
- ‘The Hybridizable Discontinuous Galerkin Method for the Numerical Approximation of PDEs‘, Dr. Manuel Solano Palma, UdeC
- ‘A coupled HDG method for the interaction between acoustic and elastic waves‘, Fernando Artaza Covarrubias, UdeC
- ‘A discontinuous Galerkin method for dissimilar meshes‘, Isaac Bermúdez Montiel, UdeC
In this regard, Alonso Bustos commented that “the seminar was very well received by the students, showing a high interest and motivation to deepen in the area of numerical analysis for PDEs. We hope that this enthusiasm will translate into the continuity of the seminar for next year, with the intention of diversifying the topics addressed and incorporating new perspectives that complement the topics already exposed during these months”.
In this same sense, CMM researcher and UdeC academic, Dr. Manuel Solano Palma, stated that “the main hallmark of SANMoMa-Graduates is to be an event carried out by and for students. This type of seminar is quite common in graduate programs in other countries, where students meet informally to discuss various topics. I thank Alonso and Benjamín for taking up this initiative, and I invite our graduate students to get involved in the organization in order to give continuity to the event”.
