which Type of constraints?

I modeled a 5-story 2-d moment resisting frame. I applied a set of lateral displacement to it. When I change a constraints from Lagrange to Transformation an error took place.
"domainChanged has not been called"
I dont know when I must call the domainChange function or why did this error occur.
thank you

you can't .. it is a bug i will fix in next version 2.2.0 .. in the menatime you can just issue another analysis command, i.e. system with the same system as before.

Thank you Dr. McKenna

You mean that error with Transformation-Handler is bug? I received current source and compiled it and used, but the problem is already exists.
So currently, how can I apply nodal displacement?
I got convergence error using “Lagrange” C-Handler, although using “Transformation” type, the analysis procedure didn’t start at all. However using “load” command, the analysis conducted well, and error occurs while I used “sp” command to apply pre-defined nodal displacement.
