2. Reference quantities and results

2.1. Reference quantities and results

Under the action of the injection of fluid at points \(A\) and \(B\), cohesive interfaces open and hydraulic fractures develop. We test the value of the fluid pressure and the vertical opening at the level of the two injection points \(A\) and \(B\) at the level of the point \(U\).

2.2. Uncertainty about the solution

The non-regression of the calculation results is checked.
