Foundation Stiffness and damping in FAST v8

Dear Jason,

at first I thank you for your prompt reply!
Yes, I still disabled all hydrodynamics but I was not sure if I have as well to disable the members because in tzhe end in both ways (disabling members YES or NO) FAST aborted. After your confirmation of members’ deletion, at first I concentrated to try neglecting the members incl. the relating joints in a way that only the section “PLATFORM ADDITIONAL STIFFNESS AND DAMPING” and acc. to the HydroDyn manual the six true flags in the section above (“FLOATING PLATFORM FORCE FLAGS”) remain with the aim of no failur. It no matters what initial HydroDyn file I use (e.g. ITI Barge, OC3 Tripod, …) because the same error message orccurs always which is written as

“FAST_InitializeAll:HydroDyn_Init: Both meshes must be committed before they can be mapped.
HydroDyn_Init: Both meshes must be committed before they can be mapped.”

Are there two the same failures? Could you please give me a hint what the reason is or could be?

Best regards,
Patrick
