On performing a modal analysis (eigenfrequencies, eigenvalues) in PowerFrame, following error appears: Floating point division by zero
Solution
Mostlikely the correlation factor φ, for taking into account modal masses, is at 0 for all load groups:
- Go the Loads window
- In the palette, click on
. - Fill out the φ factor
- 1 – selfweight and dead loads
- 0 – short period loads such as wind or snow
- 0.3 – the quasi-permanent effect of live loads
