using the pitzDaily tutorial, tried importing my own mesh and running simpleFoam to test it but received an error after computing Uz:

Update: since the residuals were so high on the velocity, I modified my initial conditions to change the wall functions to non-wall functions, mainly of zeroGradient type. Greatly reduced residuals but produces the same error
