Static Systems not calculating

[LenLindhout]

Hi All,

 

I have a problem with calculating some truss systems.
All give the error message "The static system could not be calculated".

 

In VW23 on some trusses I get "Virtual FEM support gets load"

 

In VW24 on some trusses I get "The truss system is not properly balanced"

 

8 Trusses won't calculate, all other trusses and hoist calculate normal.
Of those 8 trusses, some only give the note: "The static system could not be calculated" with no other warnings on that truss system.
Any one any ideas?

 

Thanks!

In your VW2023 screenshots is that a corner block where the hoist is attached? If so, I don't believe you can have a corner block without the adjacent piece of truss attached but @jcogdell or @Scott C. Parkermay know better.

Correct, a straight truss with a corner block does not calculate unless another truss goes off to the side. It's a long time limitation that's annoying, to say the least. You need to use a 12" straight truss vs. a corner block.

Thanks guys!

Replacing the box corner for a straight piece of truss did the trick!
Now it smoothly calculates all 112tons of equipment in a heartbeat

That is a lot of equipment!
