I'm new in nonlinear simulations in Femap and I want to know if there's a possibility to launch an analysis , starting from a previous one with a small change in the model between steps?
For examples I have a weak structure and I want to "fit a bracket" (add the bracket in the model) while the structure is deformed under an initial load case; and starting from the deformed shape, with the bracket added ,to launch a different load case.
The aim of my example is to determine the value of residual stress intraped by the bracket in the surrounding structure.
After a quick look in the examples ...the MultiSet option from the nonlinear-static analysis seems to fit to my needs .....but is it possible to do it with that model update between load cases?
Any oppinion on this matter is more than welcome!

Many thanks EndZ for your response.
I will try your solution and let you know if I handled the task!
Here is a sample model Femap neutral file that demonstrates element birth/death in advanced nonlinear solver(sol 601)
The element birth/death is not supported directly in Femap, so you must manually add the EBDSET case control entry and the EBDSET bulk data entry manually. You can see I've added those inputs in the "start text" areas for case control and for bulk data.
