Hello,
I am using the UMAT code for sand hypoplasticity provided by Prof. Masin — https://soilmodels.com/download/plaxis-umat-hypoplas-zip/. I am simulating Axisymmetric condition in Abaqus. To check the results given by the hypoplastic model for sand. I started with a simple model as shown here. I have two steps: Geostatic step and pressure step. The parameters used as shown in the figures. I added permeability for the soil (as shown below) because I need it.
The problem is when I run the model using the UMAT code, it completes without showing/implementing any step calculation (photo attached) and no results will be found. When I use one of the materials models built in Abaqus, the model runs correctly. What is the issue. could you Please help !!.
Thanks in advance.

Dear Isma..
I don’t know if it is possible to use permeability beside mechanical constant of the user defined material in Abaqus..
Why you are using permeability?
I think you are correct. I think I have done two mistakes here. The first one is the solver; I am using soil solver that defines consolidation. This should be changed to static. The second is the permeability. I will change them and see.
It is still not working Mr Kassem. Can I send you the model and the UMAT to check please.
