The physics of the simulation aren't done

when i try to generate a simulation it says the physics aren’t done, i dont know what i need to do

Hey, there does not seem to be an issue here, however, if you get a message that mentions the physics of the simulation being incomplete, this means that some of the settings are not completed. This could mean for example that you have created a boundary condition and left it unassigned, etc.
