  I'm trying to create a material to be the earth with resistivity of 600ohm.m(conductivity of 1/600 siemens/m) in maxwell so I added a new material with the configuration I just writed, but when I do it the object that I assigned this new material could not anymore stay with the solve inside configuration. the following message in the image appears. this happens to the eletric transient and dc conduction(eletric). I just realised that it has nothing to do with the creation of the material, cause the same problems happens with others materials. How can I solve this problem of the image?

  Hello, the error relates to the Material Threholds. By default, perfect Insulators have conductivity<1 Siemens/m. In this case, your material cannot be simulated with these settings. In order to solve inside, change the Insulator threshold to a value that is less than the conductivity you want to simulate. To do so:
