extract modes from linear buckling analysis

[ILTHEONE]

when doing an LBA, the following code works fine:

# Solve the static analysis
mapdl.slashsolu()
# control data written to the database
mapdl.outres("all", "all")
mapdl.antype("BUCKLE")
# option block lanczos
mapdl.bucopt("lanb", "10")
mapdl.mxpand(10)
# mapdl.solve()
output = mapdl.solve()
print(output)

now I would like to extract the eigen values / load multiplier (or at least the first one) in a variable /array.

Can someone help me?
All I tried hasn't been working...

thanks in advance!

Hi @ILTHEONE
Right after the buckle solution you can capture the mode frequency with a get_value like so:

F1 = mapdl.get_value('mode', 1, 'freq')

I'll leave it up to you to extend this to getting all 10 by looping.

Thanks Mike, work fine!
Looping is no problem :-)
It's just hard to find your way through the PyAnsyd documentation
