Computational Analysis and Simulation in General Sciences

Memory and Mission


The first informal proposal on the creation of an inter and multi-interdisciplinary association based on scientific computing applications were discussed by Reinaldo Roberto Rosa (Brazil), Fernando Oliveira (Brazil) and Horacio Wio (Argentina) during the VI Latin-American Workshop on Nonlinear Phenomena (LAWNP) held in Salvador-Ba (Brazil) in November 2003.

During the VII COLAGE (Conferencia Latino-Americana de Geofisica Espacial), March 29 - April 02, 2004, in Atibaia-SP (Brazil), was discussed the proposal on the possible foundation of a Latin-American Association of Computational Sciences (ALACC). The formal foundation meeting of ALACC held in Sao Jose dos Campos-SP (Brazil) on saturday 15 may 2004, one day before the IV Encontro Regional de Matematica Aplicada e Computational (IV ERMAC) jointed to the First Workshop on Simulation and Analysis of Complex Systems (I WSACS). During this meeting were discussed proposals for the Directory and for the statute of this association. During this hybrid meeting "IV ERMAC+" (May 20) was organized the first general assembly of the ALACC.

The main goals of that ALACC's foundation assembly were:

  1. to approval its first Directory (founder members)
  2. to approval its statute
  3. to approval the list of its founder members

After January of 2006 this initiative became a Pan-American one and the proposal was renewed during the "Escola de Verao do Laboratorio Associado de Computacao e Matematica Aplicada" held at INPE, Brazil. In its 2nd edition in 2008, the name of the association becomes Pan-American Association of Computational Interdisciplinary Sciences (PACIS) having more than 60 participants on this inaugural new issue.


The PACIS is an autonomous association that aims to promote the understanding, development, scientific and education practice of interdisciplinary sciences where the computational science is explicitly one of the methodological components. Objectives of PACIS include:

  • To establish a new emergent interdisciplinary community on scientific issues involving applications of computational mathematical modeling, correlated analytical approaches and numerical techniques, computational simulations and analysis for more accurate descriptions, predictions, experimental observations and applications of the phenomenological processes in science and technology;
  • The publication of this Journal of Computational Interdisciplinary Sciences (JCIS), for a main audience formed by: computing scientists, mathematicians, physicists, chemists, biologists, engineers, Earth and environmental scientists and others researches involved in specific applications of advanced computational methods, techniques, simulations and high performance computing.

In particular, the PACIS must provide a single forum for the computational interdisciplinary area to strengthen links between basic and applied research, theoretical and experimental methods relating to scientific computing and computational mathematics. Its goal is to bring together, in one forum, significant activities of high quality on all aspects of interdisciplinary sciences when the scientific computing is one necessary branch.
