Undefined function at the first feasible point

Hello all. I am running using parameter estimation for inverse modeling to see how transport is affected by various parameters. My set-up is a halfcircle (blob) in a rectangle (tube). I have experimental data that describes how the concentration within a blob changes over time, which I am trying to match to see which inputs are best to match it computationally. I am using Free and Porous Media as well as Transport of Diluted Species in Porous Media. I am following the COMSOL tutorial for this parameter estimation, except I am doing the integral over a 2D halfcircle to find the changes in concentration over time. I have been getting the "undefined function at the first feasible point" error. Any help on how to fix this is appreciated.
