Re: Seepage analysis

I think it will be great if we can make this become a built-in command.
In my case, we need this script for parallel analysis. Can you show us how to do this for parallel analysis?
Sure, we put it on our to-do list, and hopefully it will be available in the next version.

Re: Radial constraint

You can, by using the Local coordinate system, and Function option if the pressure value depends on the spatial coordinates (x,y,z)

Re: How to establish steel plate in LayeredShell

Unfortunately not. But are you sure you need pinching for a steel plate? Steel itself does not show pinching in its hysteretic reponse. In fact the J2 plasticity is perfect for steel.

Re: STKO 3.0 Bug

Yes, we are aware of it and it is already fixed in version 3.1.0 that will be released soon with all the issues reported by the users in version 3.0.0.

In the meantime, you can use the lines command to manually do a rectangle. Thanks for letting us know.

Re: Setting of dynamic analysis of “column dismantling method”

You are adding a force and an equal reaction... they sum to zero so it is not doing anything. Furthermore, you are doing a transient analysis without any mass! I added some mass in the element definition. I assumed a mass per unit length equal to 2.5e-9(rho)*350x250(area of columns). You can change ...

Re: mesh problem

There were some issues in your model: The first error in the mesh is because you used quadratic line elements (3-node line elements) with a beam element that wants only 2 nodes. Keep in mind that the "quadratic" order means quadratic order of interpolation for displacement and generates element with...

Re: How to establish steel plate in LayeredShell

In your Hysteretic you have the Yield strength at 380 MPa, and an ultimate strength of 557 MPa. After that the material has a plateau at 557 MPa. The initial Young's modulus from your Hysteretic material is 380/0.001768 = about 214000 MPa. Compute the Bulk and Shear modulus assuming a poisson's rati...
