MESSAGE ID : 260 ** WARNING ZERO OR NEGATIVE SUB-VOLUME

A_20330

 Hello,

I have been working on a model (wind turbines) and applying an imposed velocity on the fins, and I have an error while running:

MESSAGE ID: 260  ** WARNING ZERO OR NEGATIVE UB-VOLUME

How I can fix this problem? Model specification:

1. Boundary conditions (free on z) axel of rotation

2. Gravity load

3. Imposed velocity

Hi,

Unfortunately, this error can be caused by more than one sources, so it will be helpful to share the model, if you can, in order to review it.

If the simulation you are trying to run is Fluid-Structure Interaction, the following KB article might be useful.
