Forced Poiseuille flow(Initial velocity values)

[achodankar]

Hello Developers,
For forced Poiseuille flow, How are the initial values for velocity set? A Poiseuille force value is set to all fluid nodes. However, the initial condition plot for velocity is not symmetric. So I am curious if there is a way to check how the initial velocity values are set for forced Poiseuille flow.

Also, I would like to request the location of the code in the source codes for the following line:

AnalyticalFfromSuperF2D<T> intpolateVelocity( velocity, true );
intpolateVelocity( numerical,point );

This method is used for both interpolating the analytical and numerical values. What is the difference between this method and blockreduction2D2D method to extract the velocity values?

Thank you.

Yours sincerely,

Abhijeet

A straight forward way to finding class definitions is via Doxygen. e.g. for AnalyticalFfromSuperF2D.

AnalyticalFfromSuperF2D interpolates using the node locations as sampling points while BlockReduction2D2D performs a reduction of the resolution (there is e.g. also a BlockReduction3D2D for extracting a hyperplane, BlockReduction functors generally use interpolation functors internally).
