I'm sorry to bother you.
Hello, I have some questions about floating bodies. My stl file is a semi-submersible platform, so what do I need to set up when I set X? I only set its mass X 22 in the initial Settings, but the error appears as follows: initializing fb... Center of Gravity xg: -nan yg: -nan zg: -nan Volume Floating Body: 0 Mass Floating Body: 1.347e+07 Density Floating Body: inf Moments of Inertia Tensor: -nan -nan -nan -nan -nan -nan -nan -nan -nan 1 simtime: 0 timestep: 0.066086 t/T: 0 Volume 1: 2.4007e+06 Volume 2: 7.9933e+05 lsmtime: 0.00343 Inflow: 0 Ui: 0 Hi: 60 Outflow: 0 Uo: 0 Ho: 60 Xe: 0 Ye: 0 Ze: -1.3214e+08 Ke: 0 Me: 0 Ne: 0 Xme0 : -nan Yme0 : -nan Zme0 : -nan Kme0 : -nan Mme0 : -nan Nme0 : -nan Xme1 : -nan Yme1 : -nan Zme1 : -nan Kme1 : -nan Mme1 : -nan Nme1 : -nan Xme2 : -nan Yme2 : -nan Zme2 : -nan Kme2 : -nan Mme2 : -nan Nme2 : -nan ERROR detected by Hypre ... BEGIN ERROR -- hypre_BiCGSTABSolve: INFs and/or NaNs detected in input. User probably placed non-numerics in supplied b. Returning error flag += 101. Program not terminated. ERROR detected by Hypre ... END ERROR detected by Hypre ... BEGIN ERROR -- hypre_BiCGSTABSolve: INFs and/or NaNs detected in input. User probably placed non-numerics in supplied b. Returning error flag += 101. Program not terminated. ERROR detected by Hypre ... END So for irregular platforms, uneven density, I need to set the values in X21, 22,23,24 to make sure that he is correct. Best wishes to you. |

Hello, why did I get an INF or nan type error after importing float using STL file? For the floating body I set density, mass and center of gravity. The error is shown below:
initializing fb... Center of Gravity xg: 100 yg: 100 zg: 46.54 Volume Floating Body: 0 Mass Floating Body: 1.347e+07 Density Floating Body: inf Moments of Inertia Tensor: -nan -nan -nan -nan -nan -nan -nan -nan -nan ERROR detected by Hypre ... BEGIN ERROR -- hypre_BiCGSTABSolve: INFs and/or NaNs detected in input. User probably placed non-numerics in supplied b. Returning error flag += 101. Program not terminated. ERROR detected by Hypre ... END The running file is shown in the attachment. Looking forward to your reply. |
