• When I run this tutorial with DELL Workstation with 12 core the analysis finished at 335000th time step but in the xml file it is written that NumSteps=2000000. Is this a random number or is there a way to calculate this number of time steps?
• In this problem Quasi-3D approach is used but there is no information about the length of the pipe. At first I thought this is a periodic problem but there is also no periodic boundary condition in the xml file. Can you please clarify this point?
• Moreover, when I converted the last *.chk file to Tecplot's dat file I only see the front face of the pipe (2D) how can I add the third dimension to see the contours in 3D as shown in the link below:

• Is it possible to use Quasi-3D approach for all axisymmetric geometries like constricted 3D pipe as below:
• In the Geometry it is said that D=1. Is it unitless otherwise what is its unit mm or meters?

And finally regardless of the tutorial I want to ask that:

• Is it possible in Nektar++ to use the solution of a mesh as an initial condition of another mesh?
