Generalised plane strain using Abaqus Explicit

[CAE-boomer]

Hello again,
I am conducting a 2D simulation using Abaqus/Explicit and I want to implement Generalised Plane strain condition into my model. However, GPS cannot be used in Abaqus/Explicit, so I want to know if there is a way around this.
The first thing that comes into my mind is creating a UMAT which will mimic the thickness variation in the out-of-plane direction but I want that to be my last resort.

P.S.: The simulation NEEDS to run in Abaqus/Explicit. That is a constraint with my problem.

Thanks in advance.

More likely VUEL because you need a custom element, not just a constitutive relation. But it won't be easy. Instead, I would try modeling this in 3D, as it's quite often done with regular plane strain models. With proper constraints, you should be able to achieve the required state of deformation.
