Re: element crossing in BeamContact2D element

Hello everyone, I am currently working on a project where I want to model a cantilever retaining wall, following Wiki's example. However, I am facing a problem where the wall element crosses the soil element during the excavation process in certain condition, such as when the wall is a 10-meter fle...

Re: Display recorder don't work

hy, everyone. I'm start to use opensees 3.5.0. on tcl code (notepad++) and i have try some exemple codes. They work quiete nice but i have problems with all the DYSPLAYMODEL function. In my PC with Windows 11 home i can't see the figure or img, and also if I try a simple command, nothing happen. Li...

Re: How to simulate seismic conditions with non-uniform excitation in Opensees?

Hi All, According to my knowledge, the uniform excitation can be achieved in Opensees by calling the "UniformExcitation" sentence. But if I wanna simulate the earthquake cases with non-uniform excitation, that is, considering that the ground motion excitation of the earthquake at different bearing ...

Re: viscoelastic boundary

OpenSees does not have a specific element type for that.

You can apply viscoelastic material properties to standard elements like quad or brick elements. OpenSees has several material models. You can use the ViscousMaterial or StandardLinearSolid material models, start from there.

Re: Dynamic analysis is not convergent

I understand you're facing convergence issues with small ground motions in OpenSees. This can be tricky, but here are a few quick tips to try: Check Your Time Step: A smaller time step can sometimes solve convergence problems in dynamic analysis. Review Model Parameters: Make sure your material prop...
