Re: Free Field & Lysmer Kuhlemeyer Boundary Condition

Do you mean a research paper that describes that method, or a tutorial that explains how to do it in STKO?

Re: how to see the vibration mode

Those options in the grid editor are just parameters to set up the grid. The grid a pure graphic item and has nothing to do with the unit system. When you set the grid size = 10 (units) you are just telling STKO that the grid step for the grid-snap is 10 units. But remember that in STKO we don't hav...

Re: UpdateMaterialStage Command in STKO

The updateMaterialStage command is not directly available in STKO since we use the "parameter" and "updateParameter" commands. However if you want to use the updateMaterialStage command you can do the following: new AnalysisStep choose Model -> Misc_commands -> customCommand in the TCLscript attribu...

Re: Importing from tcl

What do you mean with "I can't use the mpco recorder command" ?
You don't know how to use it? or it doesn't work?
If it doesn't work, please post the error

Re: UniformExcitation output analysis

When you use UniformExcitation, if you plot the displacement of a node, that would be the relative displacement, i.e. the displacement relative to the ground displacement. That is, you will see your model move, but with the base fixed. If instead you use MultiSupporExcitation, then the output will b...

Re: shell element

That error says that the element module (ShellMITC4, i.e. the finite element formulation you are using) requires a quad mesh (4 nodes) while you meshed the surface with triangles (3 nodes). If you want to use the ShellMITC4, you need to do a quad mesh. By default the mesh is unstructured and triangu...

Re: how to add the wall in frame structure

Once you've designed your shell elements you can merge them with the frame structure. Once the merge is done, please check the assignements (elements, conditions...). During the meshing definition you can use the "edge seed " command to refine the mesh. This process is avaliable yust in case of usin...

Re: how to import the path file in time series

You can simply copy and paste your data from excel. Here is a gif that shows how to act.

Re: transient analysis

Of course. At this dropbox links you will find 2 simple examples of a column under ground motion. An example uses uniform excitation, while the other uses an imposed ground motion with multi support excitation. column_uniform_excitation column_multi_support_excitation Note for uniform excitation : T...

Re: how to see the vibration mode

Dear Yulu Liu,
you should choose modes of vibration both in the result and in the deformation drop down menu.
