Hello everyone,
I have an error message like this:
ForceBeamColumn3d::update() -- could not invert flexibility
WARNING - ForceBeamColumn3d::update - failed to get compatible element forces & deformations for element:...
Normally this kind of error is because the section is wrong, but I've defined the section exactly the same as I defined the rest of my sections which they work well (the rest of my section are symmetrical).
section shape:
_____________
!_________.....! Y axe : Vertical
.............!....! Z axe: Horizontal
.............!....! Point doesn't exist
.............!___!
Materials:
set acero 2
set Hormigon 1
Sections
set Sv9 3009;
set b1Sv9 110.0;
set h1Sv9 20.0;
set b2Sv9 28.0;
set h2Sv9 120.0;
set ZcgSv9 53.31; # Z gravity center
set YcgSv9 43.79; # Y gravity center
section Fiber [expr $Sv9-2700] {
patch rect $Hormigon 2 18 [expr $YcgSv9-$h1Sv9] [expr -$ZcgSv9] [expr $YcgSv9] [expr -$ZcgSv9+$b1Sv9]
patch rect $Hormigon 12 2 [expr $YcgSv9-$h1Sv9-$h2Sv9] [expr -$ZcgSv9] [expr $YcgSv9-$h1Sv9] [expr -$ZcgSv9+$b2Sv9]
layer straight $Acero 2 $As6 [expr $YcgSv9-$h1Sv9-$h2Sv9+19.0] [expr -$ZcgSv9+$b2Sv9/2.0] [expr $YcgSv9-16.0] [expr -$ZcgSv9+$b2Sv9/2.0]
fiber [expr $YcgSv9-$h1Sv9-$h2Sv9+25.0] [expr -$ZcgSv9+$b2Sv9/2.0] $As6 $Acero
}
how could I solve this error?

Try running the script without any load to see if it happen again.

Re: non symmetric section bad defined
At which time step does this happen? Could you post the rest of the code?
