An automatic image‐based mesh generation and modeling approach is applied to static stress analysis of porous materials produced by freeze casting. The scaled boundary finite element method is employed due to its seemles integration with octree meshes. Several aspects related to image processing and numerical efficiency are discussed in order to evaluate the suitability of the SBFEM in the context of modeling foam‐like samples with highly irregular microstructural details.
