Hello, I am new in Comsol and I compute a vanadium redox flow battery with serpentine channel. An error message said: Undefined value found. - Detail: Undefined value found in the constraint Jacobian matrix. There are 1 equations giving NaN/Inf in the matrix rows for the variable comp1.phil_mem. at coordinates: (0.00025,0.002), ...

Can someone help me to fix this error. Thank you in advance
