GALEANO, CARLOS; MANTILLA, JUAN; DUQUE, CARLOS  e  MEJIA, MANUEL. GENERAL PUBLIC LICENSE SOFTWARE TOOLS TO FINITE ELEMENT MODELING. Dyna rev.fac.nac.minas [online]. 2007, vol.74, n.153, pp.313-324. ISSN 0012-7353.

This work presents the results of a review made to several programs with GPL licenses for finite elements modeling. This study allowed to make the characterization of these programs having into account criteria like the type of allowed analysis, the compatibility with CAD programs, the type of offered support, the update of the versions, the type of implemented user interface and the learning curve for new users, among others. Later three different cases are studied, which were modeled with finite elements using different GPL programs. In the final part of the document the results obtained with free software are compared, with a commercial program (Ansys), and with the analytical models derived from the solution of the differential equations that governs the particular phenomenon, obtaining an acceptable convergence between all of the results.
