Can Anura3D combine 2D axisymmetry, single-point two-phase coupling, and external constitutive models in one case?

[DingtaoYan]

Hello everyone,

I would like to confirm whether the current Anura3D framework can support the following combination within a single case:

• 2D axisymmetric model
• single-point two-phase coupling for submerged saturated soil
• partial drainage during penetration and subsequent consolidation after stopping penetration
• an external / user-defined constitutive model

My goal is an axisymmetric penetration problem followed by consolidation, so I need to know whether this workflow is already supported by the current framework.

More specifically, I would like to clarify:

1. Can 2D axisymmetric analysis be combined with the two-phase coupled formulation for submerged saturated soil in one case?
2. Can this also be used together with an external constitutive model?
3. If yes, do I only need to implement my own constitutive model through the current constitutive-model interface / ESM, without modifying other parts of the source code?
4. Or, for this kind of partially drained penetration + consolidation problem, is a full 3D model still required?

I am not asking about numerical accuracy yet. At this stage, I only want to confirm whether the present Anura3D architecture already supports this combination of features.

Thank you very much.
