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

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.
