Which software is suitable for modeling anisotropic stress behavior of different rock variants during thermal heating? COMSOL/ABAQUS/ANSYS
If COMSOL, then which module should be proceeded with for 2D and 3D modeling of thermal and stress distribution in rock variants.
Dear Dr. Sinha,
If you want to simulate thermal heating of different types fo rocks and also model easily their mutual contacts, I think that Ansys Rocky is a viable solution.
Ansys Rocky is a software tool that specializes in simulating granular and particulate material behavior using discrete element method. While it is predominantly used for modeling the motion, interaction, and breakage of particles in granular systems, it does not inherently handle continuum mechanics or thermal simulations like traditional finite element analysis software such as Ansys Mechanical. However, it can be combined with other Ansys modules for modeling the thermal heating and subsequent stress distribution across different types of rocks. The advantage is that this module can handle the contacts quite well.
However, if you have a 2D or 3D domain which is split in different sub-domains made up of different rocks (different properties for each sub-domain) and you want to calculate the stress distribution under thermal heating, maybe a simple Thermal transient analysis in Ansys Workbench should work; however, you should couple this module with Transient structural in a way to calculate also the desired stress distribution.
The same can be done using Comsol Multiphysics (maybe it is also easier than using Fluent), where the Static Structural module (used to investigate stress and strain fields) can be combined with Thermal modules.
Best regards,

PeriLab is able to model it as well. It cost nothing and is open source.
