Schematic illustration of the computational domain of the moving boundary initial value problem for tumor growth. The blue area (\({{\rm{\Omega }}}_{1}^{t}\)) represents the tumor cells, the light gray area represents the ventricles, the red area (\({{\rm{\Omega }}}_{2}^{t}\)) represents the remainder of the brain, and the dark gray represents the area outside of the brain.
