Re: Viscous Damper : Damping force vs. Damper displacement

I am unable to plot Damping force vs. Damper Displacement response after conducting the Nonlinear Time History Analysis (NLTHA) You correctly chose material.strain and material.stress in the MPCORecorder. That is exactly what you need to obtain a Gauss-Point result of all the uniaxial materials ins...

Re: Convergence Error

Try to solve 1 issue at a time. Start with the modal + pushover. I cannot help you with the comparison to SAP2000. You have to make sure that everything match between them, to expect the same exact result. Furthermore, you have nonlinear materials and pre-stress, try to understand how does SAP handl...

Re: Error in Analysis

Dear Zeeshan Bhat, the SectionForceDeformation* getSectionForceDeformation(int tag) - none found with tag: 0 is just a warning. It happens because the MPCO recorder uses an iterative process to guess how many sections are inside an element, just for output purposes. Don't pay attention to that, your...

Re: Material Property (Damage TC3D)

1. Taking into account non-smooth transition between positive and negative failure surfaces, numerical problems may arise in case stress condition hits the region of the surface connection. How does the numerical algorithm deals with this zone and how can stress-strain evolution can be described th...

Re: Question about analyses command

If you do just 1 analysis it does not make any difference.
In terms of results it does not make any difference either.
It is only used by the MPCO Recorder to separate each analysis into different model stages
