Asymmetrical aluminium mullion software calculation (replacing Orand Beam 2D)

[3riders]

I'm using Orand Systems Beam 2D for a while. However, the software isn't available to purchase.

I know there is some threads on this issue here, but they are always referring to symmetrical beams. In aluminium windows industry, mullion (beams) are always asymmetrical, so I'd like to find a good software to be able to determine :

- Deflection
- Top fiber constraint
- Bottom fiber constraint

All under specific weight.

I look at :

- Beamchek
- Beampro
- Mastan2
- etc.

And none of these can be use. Please help!
