I have performed BareHull simulations of a ship in Star CCM+. I have defined a field function to calculate the wake fraction (1-vx/Vvessel) on the propeller plane. However, when I try to get the report, I get the following error message:

Part Value Errors

------------ ------------ ------------------------------------------------

Virtual Disk 0.000000e+00 unable to compute, undefined ratio

------------ ------------ ------------------------------------------------

Total: 0.000000e+00 no data, incomplete computation, undefined ratio

I also cannot see the contours in the scalar scene as well.

However, when I run the simulations for just 1 iteration, I can have the report and the scalar scene.

And If I save and close the simulation. I am able to get the report and scalar scene again.

What can be the reason for this?
