Skull Cave and Valentine Cave cross-sections for finite element limit analysis software (OptumG2)

The data include cross-sections for numerical calculations within the framework of the finite element limit analysis method, developed using the OptumG2 software. In addition, the results of numerical analyses presented in the publication "Stability and Collapse Analysis of Terrestrial Lava Tubes under Irregular Shapes: Case Study of Skull and Valentine Caves" by Marcin Chwała, Maciej Bodlak, and Patrick Whelley, submitted to the journal JGR: Planets, are provided. The nomenclature used is consistent with that of the manuscript
