SOL 103 not getting 6 rigid modes

Well, you will need to provide a lot more info if we are to help out :)

Are there any intended constraints? Did you turn on GROUNDCHECK (SET=ALL)=YES to see if there is grounding occurring?

How many rigid body modes are you getting?

The strange thing is that when I use a limit from -1 to +1 for frequency range I only get 5. When I ask to get the first 30 modes I get all 30 including 6 rigid body modes

Hi Don,

How can I send you the bdf file? Is there a secure server to deposit it?

Let's move this to an official support case... I'll open it and send you an ftp link for a secure server.
