esys-escript running soil mechanics simulation

Asked by Jiayao Wang

Hi, I just discovered esys-escript a couple of days ago, and my understanding of the software is that it's fundamentally a PDE solver.

If I want to simulate soil mechanical problems such as triaxial tests, 1D consolidation tests, etc., I have to abstract soil mechanical problems into a set of PDE functions and use esys-escript, correct? I also have to write my own constitutive soil models (e.g., Drucker Prager model, Mohr-Coulomb model, etc.), right?

To better ask the question, take some other FEM softwares as examples (e.g., Abaqus, Plaxis, Optum G2/G3, OpenSees), in these softwares, I only need to build the geometry of the model, pick a constitutive relation, apply load (boundary conditions), and it will give me the distribution of stress/strain, displacement, etc.

So, to accomplish the same goal, in esys-esript, I will have to input a set of PDEs that represent the mechanical problem, right?

I am just seeking for the possibility of esys-escript using in my research.
Thank you.

Hi Jiayao,

esys-escript comes with code for several canonical mathematical models used in geology. These models are outlined in the Models chapter of the userguide. It is also possible to write scripts that solve custom models, if none of the available models are suitable for your project.
