Explain step by step
 

3) The problem is related to the modeling of a 2D incompressible flow of fluid through a curved pipe (so-called elbow). Start Docker Desktop and Command Prompt and run OpenFOAM container. Copy the elbow case from tutorials tutorials/incompressible/icoFoam/elbow to your working directory on a hard drive. Change to an elbow folder and run this case. The CFD simulation will be performed and time folders 0, 1, 2, 10 seconds will be created with data files for pressure p and velocity U. Start ParaView and load the elbow case. Report the screenshots of color maps (Surfaces) of pressure (p, Pa), velocity magnitude (U, m/s), and velocity components (Ux, m/s and Uy, m/s) for time moment of 5 seconds.
