A front-fixing numerical method for a free boundary nonlinear diffusion logistic population model

Piqueras-García, Miguel Ángel; Company Rossi, Rafael; Jódar Sánchez, Lucas Antonio (Elsevier, 2017)

[EN] The spatial temporal spreading of a new invasive species in a habitat has interest in ecology and is modeled by a moving boundary diffusion logistic partial differential problem, where the moving boundary represents ...
Computing positive stable numerical solutions of moving boundary problems for concrete carbonation

Piqueras-García, Miguel Ángel; Company Rossi, Rafael; Jódar Sánchez, Lucas Antonio (Elsevier, 2018)

[EN] This paper deals with the construction and computation of numerical solutions of a coupled mixed partial differential equation system arising in concrete carbonation problems. The moving boundary problem under study ...
Numerical analysis and computing of free boundary problems for concrete carbonation chemical corrosion

Piqueras-García, Miguel Ángel; Company Rossi, Rafael; Jódar Sánchez, Lucas Antonio (Elsevier, 2018)
