Default timeVaryingMappedFixedValue problems within rhoCentralFoam for Blasius Solution

joshkellyjak is on a distinguished road

I'm trying to simulate viscous flow over a flat plate and use the timeVaryingMappedFixedValue boundary condition to set the inlet velocity to be equal to the velocity profile calculate using the Blasius solution. However, when I use this BC I either get a strange wave that forms at the start of my domain, as can be seen in the image.

What can be causing this and how can I eliminate this?

I think it may have something to do with a negative initial temperature error I was experiencing when trying to implement the timeVaryingMappedFixedValue BC?

Thanks in advance for your help
