Choosing right algorithms and test commands

Hi, I have a problem with my model. Is there any way to choose right algorithm and right test command to avoid convergence problems? I have checked OpenSees examples and copied algorithm changing loops, but I still have convergence problems. I tried dividing analysis time into many segments (1/20 of...

about fiber section segmentation

Dear everyone, I would like to ask you a brief question. Is it reasonable to discretize rectangular (or square) reinforced concrete section with many segments along the y-axis and very little segments along the z-axis? (extreme eccentricity or irregularity is not considered in this building) example...

P-Delta effects and leaning columns

Dear I modeled a 2-D RC frame, and considered the leaning column for P-Delta effects. I would like to ask 2 questions: 1) If I assign "geomTransf PDelta $transfTag" to non-linear column element, do I have to define leaning column to consider P-Delta effects? 2) If the 3D model is full of g...

Dear vesna, Thank you for your reply.

I'll test the TwoNodeLink element alone as you told me.

Thanks again.

Dear vesna, Thank you for your reply. I defined local axes of the TwoNodeLink element. but I'm still getting similar errors Error message: WARNING TwoNodeLink::setUp() - element: 1122 ignoring nodes and using specified local x vector to determine orientation WARNING BandGenLinLapackSolver::solve() -...

Having a problem with TwoNodeLink element, please help

Hi, I'm trying to model slippage problem(which is caused by pin hole diameter and pin diameter differences) in joint connections. I tried 'TwoNodeLink element' to connect an element to joints, but I get LAPACK errors. It's been two weeks since I got stuck in this problem. Please help me.. Here's my ...
