Hi,

Is there a way to record modes of vibration with MPCO recorder?

I didn't use the STKO pre-processor to build my model; I'm just using the MPCO recorder to get an overview of my model. I need to see the shapes of the different modes, and I'm wondering if the MPCO recorder supports this.

I use ...

There could be many reasons.
But your model has not been done with STKO and we cannot go through 70 thousand lines of code to find the issue. I'm sorry but I think you should create a smaller version of your model so that it's easier for you to debug it


No worries, you are right! I've started ...

Dear STKO Team,

I am currently working with a model-scale pile-soil-bridge model and trying to validate it using shake table experimental data for the same configuration. My dataset comprises accelerometer and displacement sensor readings.

Upon analyzing the acceleration response from my numerical ...

Normal Penalty (kN): 1E12
Tangential Penalty (kT): 1E6
In a contact element, those values are penalty values. It means that in theory the should be INFINITY, but in practice, you can't, so you chose a "high enough" value. And it really depends on your model. For example, if the typical stiffness ...

Dear STKO team,

I am currently working on simulating the interaction between double rubber pads located between the pier top and the deck in my OpenSees model. I came across an element ( zeroLengthContact3D ) on the OpenSees wiki that seems appropriate for this purpose, and I have incorporated it ...

Thank you very much, I can confirm this has resolved the problem.

Are there any drawbacks of using customDomainChange procedure for my analyses at this time?

Dear user,

I am using mpiexec.hydra.exe to run my model in parallel in order to speed up my analyses. This process generates multiple MPCO files, with names such as "model.part-0.mpco", "model.part-1.mpco", "model.part-2.mpco", "model.part-3.mpco", and "model.part-4.mpco", based on the number of ...
