Morning to all.  
To assign a Power to object, PrePoMax has three ways:

- Concentrated flux
- Surface flux
- Body Flux

I use often Surface and Body flux, where i have to specify the power in mm^2 or mm^3, and it works very well.

When can i use the “Concentrated flux” ? It is very very slow and creates many points.

Thank you very much.

Concentrated flux, just like concentrated force, is meant to be applied to individual nodes, not whole surfaces/volumes.
