Hi STKO team. first of all I wanted to thank you in the process of learning opensees and modeling.
I am modeling a soil slope based on this example.
(https://opensees.berkeley.edu/wiki/inde ... s_of_Slope)
I am having trouble implementing the Lysmer Dashpot and interactions as it comes out in the example.
When I activate the mp constraint EqualDOF in the constraintpattern the analysis does not start and gives the image error.
What do you think is the cause of this problem?
I would appreciate if you can review the model and see where the error is.
Best regards
equalDOF- Lysmer Dashpot.

Re: equalDOF- Lysmer Dashpot.
The error says that node 127 is not in the domain at the time you input the mp command.
This happened because you are doing construction-staged analysis (you are using the modelSubset) to add pieces of the models one at a time. But you added only the soil domain, not the other 2 vertices, so they will never be in the domain.
You either using another modelSubset command to add the other vertices to the model before adding them into a MP constraint, or just remove the modelSubset so that the whole mesh will be added to the domain from the very beginning
