Hi,<\/p>\n

I am not very conversant with ANSYS AQWA but i am working on FPSO mooring line analysis. The following errors were encountered while running the Hydrodynamic response:<\/p>\n

    \n
  1. The structure keeps sinking completely into the fluid domain.<\/li>\n
  2. Aqwa-librium iteration failed to coverge after the 500 requested steps (as shown in the last screenshot).<\/li>\n
  3. The selected structure no longer exists. Please update your selection.<\/li>\n<\/ol>\n

    I can try to fix the last one but in the sinking of the fpso completely into the fluid domain is what i cannot understand. I have tried reducing the mass of the structure, the mass\/length of the mooring lines and even the area but still cannot solve the challenge.<\/p>\n

     <\/p>\n

    Please, if there is any way you can help me resolve this, i will be grateful.<\/p>\n

     <\/p>\n

    Thanks.<\/p>\n

    This is the mooring line configuration used in this analysis.<\/p>\n
