Undrained Response in abaqus

[Trisha_abaqus]

Hello,

I am wondering other than using C3D8P element to simulate a undrianed response, is there any other element in ABAQUS element library. Similar to Fluid Solid Porous Material in OpenSees.

Thank you for the response.
Trisha.

Why aren't the built-in pore pressure elements in Abaqus sufficient for your purpose ? What are they lacking that the aforementioned elements in OpenSees have ?
