Hi @akpcorp, it seems you are using the wrong analysis type. You should use “dynamic analysis - advanced”.  
Best,

Hi @akpcorp ,

As stated by the error you have assigned two materials to one entity and another entity has no material at all. Make sure you only assign one material to the mentioned entity and add a material to volume 3 . You may then proceed with your simulation setup.

Cheers,

Jousef

And, with a couple of Reflect filters you can have the complete quadcopter simulation. 😀
