Re: having problem building OpenSees in OS X 10.11.1

I am getting a similar problem. Was this ever resolved?

I think it has something to do with El Capitan and the OpenSSL libraries.

Re: Error with uniaxialMaterial Hysteretic in v2.5.6

SP, there is a static analysis which runs fine before I run the transient analysis. The warning comes during the transient analysis.

Re: Error with uniaxialMaterial Hysteretic in v2.5.6

This warning occurs with a transient analysis only. Here are my analysis commands:

Re: Error with uniaxialMaterial Hysteretic in v2.5.6

Hi Frank,

I'm getting this error now.
WARNING: CTestEnergyIncr::setEquiSolnAlgo - no SOE

Is this related to the recent update or something on my end?

I was not getting this with previous builds.

Thanks,

Nasser

Error with uniaxialMaterial Hysteretic in v2.5.6

Hi, I think there is bug with the latest version of OpenSees (2.5.6). The Hysteretic Material Model does not seem to be working. Try this: uniaxialMaterial Hysteretic 310001 41.800000 0.001441 52.250000 0.014414 57.475000 0.028828 -41.800000 -0.001441 -57.475000 -0.014414 -62.700000 -0.028828 1.0000...

Eigenvalue Analysis of Degraded Stiffness Matrix

Hello,

Can you run an Eigenvalue analysis in the middle of a transient analysis to figure out the elongated period of your building at each time increment.

Thanks

Re: Mumps

I tried that and it does not seem to work. Any other suggestions?

I also tried to run it on NEESHub and got the same error.

My code is below:

Digit limit on ID Tags

I was wondering if we could easily increase the maximum number of digits a tag ID can be in OpenSees. The currently limit is at 9 digits which can be limiting if you are working with large models and decide to have a node/element numbering sequence that corresponds to the grid number the node/elemen...
