LAGE-BONIFACIO, Aldemon et al. Thermo-hydro-mechanical model parameters adjustment via a distributed scientific workflow system. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.200, pp.46-52. ISSN 0012-7353.  http://dx.doi.org/10.15446/dyna.v84n200.56156.

This work presents a numerical approach for the automatic adjustment of parameters of the Mazars Damage Model, applied to a thermo-hydro-mechanical modeling of concrete structures. The procedure is based on a Scientific Workflow System (SWS) that addresses the combinatorial universe of adjustable parameters by minimizing the number of simulations required for optimized results. Not only does SWS improve efficiency, by also makes the strategy easier when compared to manual procedures. The adopted algorithm is developed in an intuitive script language and employs a distributed computational environment. Comparison to experimental data indicates that the proposed methodology was efficient and effective in improving the analysis, by minimizing errors and saving processing time.
