Hello,
I am trying to evaluate the behaviour of a 2D plain strain "cut and cover" tunnel section when I apply static loads (by the moment)
I am using XFEM method in order to evaluate the cracks through the reinforced concrete material. The model has been meshed by CPE4R elements (Quad)
I have modelled 2 types of steps: Geostatic in order to apply the initial stress state and Static, general for the rest of steps.
I am trying to solve the error below:
A xfem analysis with pore pressure degrees of freedom is not supported.
