sliding between blocks

Hi all,

is it possible to slide these two blocks one on the other and get a reaction compatible with the friction force (i.e. N*mu)?
As it is now, it does not appear to work correctly.

I appreciate any help you can provide.

Raffaele

Constraints between two walls

Dear STKO team,

I am attaching a model of a concrete structure that is made of two walls at a certain distance from one another.

The two walls are connected with some rebars that can be idealised with an interaction to which we can assign either equal dofs for horizontal displacements or as rigid ...

How to fix solid faces

Dear STKO team,

I am trying to impose fixities on faces of a solid. Can you help to correct the bold green part of the script below? Let say that I am interested in fixing the face 3 of the solid 2.

con = MpcCondition()
con.id = doc.conditions.getlastkey(0)+1
FIX_Vector.append(con.id)
con.name ...

MpcAttributeType.QuantityMatrix

Dear STKO team,

can you please let us know how the MpcAttributeType.QuantityMatrix is populated from the STKO preprocessor?

We are trying to implement automatically the Pressure Independent Multi Yield material as shown below:

meta = doc.metaDataPhysicalProperty('materials.nD ...

Running postprocessing on multiple results

Dear STKO Team,

I am currently running the same postprocessing script on multiple output databases generated by STKO for different accelerograms.

The general form of the instructions is:
1. OpneDatabase --> App.runCommand("OpenDatabase", "RECORDERS.mpco")
2. Instructions --> runpy.run_path(path ...

Re: POST PROCESSING OF TIME-HISTORIES FOR LARGE STRUCTURES

Dear STKO team,

thank you for the swift reply.

I have an additional question.

Is it possible to run the for loop on time steps as a parallel process? Is there any approach to run the worker and the thread on the multiprocessor?

I think using a multiprocessor approach may speed up the ...

POST PROCESSING OF TIME-HISTORIES FOR LARGE STRUCTURES

Dear all,

I am writing to ask for some clarifications on the postprocessing for large structures where you can have multiple materials (that needs to be verified against different capacities); moreover, you may not know in advance the number of elements, the number of section for each beam, and the ...
