Error on simulating Lithium-Ion tutorial

Hello,

i was trying to do the tutorial of simulating a 2D lithium-Ion battery (www.comsol.com/showroom/gallery/9981/), b ut when i try to execute my simulation i get the following errors:

Failed to evaluate variable Jacobian.
- Variable: material.tplus
- Geometry: 1
- Domain: 3

Failed to evaluate variable Jacobian.
- Operator: mean
- Geometry: 1
- Boundary: 5 8

Failed to evaluate variable Jacobian.
- Operator: mod1.liion.tplus
- Geometry: 1
- Boundary: 5 8


I dont find the error. i compared it with the done tutorial model and i find no difference and it executes perfectly. i Always get the error and on materials it shows me the error that it wants for the electrolyte the electrical conductiviy and for the electrode materials electroltye conductivity and transport number, which makes no sense.
If someone could give me a hint what the error is, it would be great.


Greetings

Heinz
