                                                    Hello,
I have the same problem. I constructed a new physic in COMSOL physic's builder and added 2 domains for simulation (first, I had only one domain and everything worked fine). No, by adding the second domain, the error occurred. The material properties are given in the material node, and selected by the "Material Property" option in the physic's builder for each domain.
Can anybody help me?
thank you very much

                                                    Hi,
This is probably caused by that you have added a material where one of the properties depends on e.g. temperature or pressure.  If the domain feature in the physics interface cannot pass down the missing parameter,  you will get this error. The quickest solution is then to replace the offending material property with a constant value. 
Regards,
