2. Reference quantities and results

2.1. Reference quantities and results

Under the action of injecting fluid into the cohesive interface on the left edge of the domain, the cohesive interface opens and a hydraulic fracture develops. We test the value of the fluid pressure and the vertical opening at the points \(A\), \(A\text{'}\), \(B\) and \(B\text{'}\) at the end of \(t=10s\) of injection.

2.2. Uncertainty about the solution

The non-regression of the calculation results is checked.
