Re: Beam-to-Solid-Bar-Slip

I generated a fiber color map in the post-processing interface. Why are the fibers marked in the picture discontinuous? A fiber color map is always discontinuous, in the sense that we plot a series of points (fibers) at each gauss points. Of course in the larger elements they seam more "discontinuo...

Re: Stko is closed after meshing

Could you share your model?

It means that there is something wrong with the geometry and STKO cannot compute the Delaunay mesh

Re: L section

dimensions of cross sections are in inches Do not pay attantion to the unit system, because OpenSees does not have the units... Just enter the values consistently with the unit system you are using in your model In addition, there is not inertia product Iyz YOu are right, the Elastic section in Ope...

Re: Time History Analysis

some elements support the "RayleighForces" output.
However not all of them, and also they do not clearly explain what the components are.

Re: How can visualize horizontal , vertical stress in soil domain

That's because the SSP brick elements do not support the "material" keyword before the "stress" keyword (they have only 1 integration point)

So you can simply use the custom results an input "stress" only:

Re: Cannot show pore pressure response

YEs this is exactly what I meant.
It's not a problem if you see a pressure = 0 at the bottom layer of absorbing boundaries (those nodes are not real soil nodes).
The important thing is that what happens inside the SOIL domain is what you expect!
good job

Re: Dividing geometries

If you want to "explore" the "embed" option, i.e. attaching to un-compatible geometries, you can see how we did it in the last webinar with the soil-foundation-structure interaction. In that webinar the soil under the building and the surrounding soil were not merged, but attached using the ASDEmbed...

Re: Adding nodal mass

In Condition-> Mass you can choose among: NodalMass (mass assigned to a vertex) EdgeMass (mass per unit length, assigned to an edge) FaceMass (mass per unit face, assigned to a face) VolumeMass (mass per unit volume, assigned to a solid) The last 3 are automation that allow you to assign a distribut...

Re: Nonlinear Dynamic Analysis

Element Load does not seem to have been applied to the displacement of the x-axis. It's because you forgot to reset the pseudo-time to 0 after the gravity analysis. In this way the time of the dynamic analysis starts from 1 sec, when the horizontal load is already finished! Also pay attantion to th...
