SFD Meshing Error - Request for Assistance

Dear SIMULIA Expert,

I am currently working with an SFD model of a ship structure and have encountered an issue during the meshing process (on a 3DEXPERIENCE platform).

Specifically, I am repeatedly receiving an error message that states:

"Lay down, operator.

The body to be operated on is not on the input skin body.

Project the body onto the skin."

I am reaching out to seek your expertise in understanding why this error is occurring and to inquire about the best possible solution to resolve it. Your guidance and insights would be greatly appreciated.

Thank you in advance for your assistance.
