Is it possible to generate pore pressures in an axisymmetric model? I am running an undrained triaxial test code, and I am unable to generate pore pressures in the model if the command “model configure axisymmetry” is enabled.

Hi Cristian,
Axisymmetry logic is not yet complete in FLAC2D, and we will be working on enabling it for fluid, thermal and dynamic calculations in future updates/releases. How do you generate pore pressure in your model? If it is through the fluid module, this currently won’t work.
This is interesting @apyatigorets I did not know this about the axisymmetry logic. Worrying.
However, @CrissBidermann, I can simulate undrained triaxials with pore pressure generation fine using for instance the NorSand model in axissymmetry using a high fluid modulus in FLAC2D.
e.g. zone gridpoint initialize fluid-modulus 2.0e9 ; Pa
