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?
