Abstract Scope |
ODBP is an open-source, Python 3 based post-processing tool for manipulating Abaqus output database (.odb) data. Abaqus is a popular commercial Finite Element (FE) solver used to simulate and model additive manufacturing (AM). Abaqus stores the results of its simulations in the proprietary .odb file format. ODBP uses the Hierarchical Data Format (.hdf5) file format to efficiently store .odb data in a portable, accessible format. ODBP also uses Polyscope, a lightweight, robust three-dimensional visualization tool to emulate Abaqus’ three-dimensional volume-mesh plotting and improve on these capabilities, more easily viewing subsets of the dataset, such as only the melted section during deposition. ODBP’s open-source, portable nature has established a framework that can be used by collaborators across fields from machine learning to computational fluid dynamics. Currently ODBP is being leveraged to compare thermal AM FE simulations to experimental measurements from a pyrometer. |
