Hello everyone,
I am analyzing a soil-pile and superstructure system under dynamic loads. For this reason, I am recording the many kind of output. The load input files are not being read if the number of recorders were defined above some limit. Therefore to take all the required output, I have to perform the analysis two times.

Is there any way to change the limitations in the number of defined recorders??

thank you,

Thank very much you for your answer and sorry for my delayed reply. I am trying to analyze a soil-pile system. The model consists of SSPbrick elements for soil domain and elasticBeamColumn elements for the pile. I was using "BandSPD" and "RCM" commands for system and numberer definitions, respectively. I have changed those properties to SparseSYM and RCM/Plain and then the analyze time has decreased to around 300 seconds. I think the problem with analysis time has been solved for now. Thank you for your attention.

Hello everyone,
I have a 3D model with elastic material properties having around 2100 node and 6000 - 7000 degrees of freedom. The time history analysis of this model takes around 50 minutes for a 3-second analysis duration selecting the time step as 0.005 (OpenSees Version: 3.3.0). The computer used in the analysis has an IntelCore i7 processor and 16 GB of ram memory.
The analysis seems to take a long time. Is there anyone analyzing such a 3D model in Opensees? For a comparison, I would like to ask how long does it take? I am trying to understand whether I am doing something wrong/missing.

Thank you

Hello everyone,

I need to know the Gauss Point orientation for the simple Quad Element. How are the Gauss points ordered for this element?

Thank you

Hello, I am trying to practice the “CycLiqCPSP” constitutive model for the analysis of a soil-pile model. I have used the material parameters given in the corresponding paper. However, for a gravity analysis of the 2D soil model (without pile) –i.e. more simple case, I have encountered with convergence problem. Can anyone have an idea about the problem or Is there any example using “CycLiqCPSP” constitutive model for static and/or transient analysis?

Hello everyone,

I would like to ask whether a 15-Node element exists or not. It does not appear in the element library but has anyone written a 15 node element for Opensees?

Thank you
