Thank you, frank.
Can you please share the amd lib file for windows developer, btw?

I found that the AMD number algorithm is not constructed, yet.
When it is loaded, the ops returns

AMD::AMD()

THank you for your time.

sorry , i have made some mistake.

Could you please check this script, which i just want to display the periods of structures before and after the gravity load analysis. It gave the warning.

[\code]

This script works well on the previous version of OPS.
For now, the opensees 2.1.1 give out the warning,
WARNING DirectIntegrationAnalysis::eigen() - no EigenSOE has been set

the warning will occur in the script when the eigen command loaded twice, for both static analysis and dynamic analysis. Maybe some default classes were omitted in the previous modification.

otherwise, did i do the wrong operation procedure?

Thanks.

something different of the eigen command compared with previ

something different of the eigen command compared with the previous version.

when i sourced some old but worked well tcl script, the eigen command gives warning like this:
WARNING StaticAnalysis::eigen() - no EigenSOE has been set

this warning promoted after the gravity load analysis procedure.

whenever and whatever the SOE and Analysis classes specified, the eigen command inputted and the warning information displayed.

Could you please check it?

Thanks!

thankyou!
i have search the forum.

min/max command ? Isn't it the tcl inherent command in tcl mathematic lib, or the additional command implemeneted by Opensees?

Otherwise, are you meaning the max/min material? i dont think it is a solution for the issue of cut off the strain larger than 1%.

By the way, except the hystereic material in openSees, the materials, like steel03,steelMP,reinforcingsteel and hardening, do not consider the failure when the strain become larger than 1%, does they??

i will try the hysteretic material first and wait for your suggestion, thank you!

How can i make the steel fiber to be failure when its strain

How can i make the steel fiber to be fail when its strain is larger then 1%?
Steel01 and steel02 both illustrated as there is no material failure .
Since that, the behavior of some steel structure model are not like a real one in the failure nonlinear region.

make sure the path includes the mpi bin folder
