iGP (interface between GiD and PFLOTRAN) is a recently developed tool that provides a fully integrated pre- and post-processing environment to PFLOTRAN. In the following webcast, Aitor Iraola describes how a PFLOTRAN reactive transport model can be readily set, solved and post-processed using iGP.



Before joining our company as a staff consultant, Aitor spent a six months internship at Amphos 21, where he worked (hard) on the development of a pre- and post- processing interface to PFLOTRAN.

Aitor’s thesis laid the ground for a fruitful cooperation with the International Center for Numerical Methods in Engineering (CIMNE), a research and development organization based in Barcelona (Spain). One the CIMNE’s key products, GiD, was used to provide a customized pre- and post- processing framework to PFLOTRAN. Aitor’s work also greatly benefited from the advice and support of the PFLOTRAN community.


The tool: iGP

iGP stands for interface between GiD and PFLOTRAN.

GiD is a powerful universal, adaptive and user-friendly pre- and post-processor for numerical simulations in science and engineering and is developed by the International Center for Numerical Methods in Engineering (CIMNE).

PFLOTRAN is an open source, state-of-the-art flow and reactive transport code.

iGP provides a powerful and user-friendly pre- and post-processing environment to PFLOTRAN. In iGP, the user can implement complex geometries, define different regions, set different materials, apply different boundary and initial conditions, mesh the domain (using structured, semi-structured or fully unstructured grids), run PFLOTRAN and post-process the results.

In the following webcast, Aitor explains the steps to set, run and post-process a PFLOTRAN model using iGP.
