Hello,

The error message I am getting is:

Invalid numerical input for file “source\SampleBeam.bmi”.

The error occurred while trying to read iyz_tip.

Aborting BModes.

I have all of the “blade-tip properties” set to zero, as they are in the sample input file on the BModes user guide:

--------- Blade-tip or tower-top mass properties -------------------------------------

0. tip_mass blade-tip or tower-top mass (kg)

0. cm_loc tip-mass c.m. offset from the blade axis measured along the tip section y-axis (m)

0. ixx_tip blade lag mass moment of inertia about the tip-section x reference axis (kg-m^2)

0. iyy_tip blade flap mass moment of inertia about the tip-section y reference axis (kg-m^2)

0. izz_tip torsion mass moment of inertia about the tip-section z reference axis (kg-m^2)

0. ixy_tip cross product of inertia about x and y reference axes (kg-m^2)

0. izx_tip cross product of inertia about z and x reference axes (kg-m^2)

0. iyz_tip cross product of inertia about y and z reference axes (kg-m^2)

So why does it get confused on the last line of this section?

Thanks,
