there are no modes in the specified range

[cdcmd]

Has anyone ever met this note in their output files (in my case buckling) and could give me any idea how to solve the problem?

"there are no modes in the specified range"

resulting from this note, this warning pair appears in the output (no way, no result, clearly):

_
no data sets on file.

_
load set not found on result file.rst.

This is what I found about a self-desk forum:
"in a linear critical buckling analysis, the processor may fail to find a solution if the stiffness ratio is large. this can occur when smart bonding exists in the analysis and a large penalty multiplier is used. try reducing the penalty multiplier."
but not working with contact elements I do not have the pallida idea of where/how should I/I could/can act on penalty multiplier.

Thank you!

you specified an eigenvalue range within which to search.
for example you have requested that the load multiplier (eigenvalue) be between 0 and 10, but within the specified range the structure does not go in buckling. you have to increase the range, or alternatively, increase the load.

Thank you very much for the answer,

but I did not specify any multiplier. You mean ldmulte right?
Therefore it is possible that for some configurations the multiplier 0 is sufficient (4 out of 8 work) and for others not?

thank you anyway, now I try and in the case if I can solve
