Sequential Simulation not Continuing

d_con13

I have a model in which I want to start with a fixed joint to maintain initial geometry, and then release after a short time in motion. Per MV-1051, I have added a template file as below, however when I save and run (and can confirm that the joints activate and deactivate in the run log, see italicized log snippet), the second half of the simulation does not appear to run and jumps right to the stop (see italicized snippet). I am not sure what is causing the second part of the sequence not to proceed - any help would be greatly appreciated.

<Deactivate
    element_type = "JOINT"
    element_id   = "301001"
/>

<Simulate
analysis_type      = "Transient"
end_time       = ".05"
print_interval = "0.001"
/>

<Deactivate
    element_type = "JOINT"
    element_id   = "{j_init_fix.idstring}"
/>

<Activate
    element_type = "JOINT"
    element_id   = "301001"
/>

<Simulate
analysis_type  = "Transient"
end_time       = "5."
print_interval = "0.001"
/>

<Stop/>

Hello @d_con13 

It is hard to figure out a reason why that does not work without looking at the model? Is it possible to share the model ?

What type of joint is "301001" ? If its an inplane or planar joint, you may have to use the keyword "JPRIM".

Regards

Unfortunately I don't think I can share the rest of the model, but it is a relatively simple crank-slider type assembly consisting of two bars, one on a rotating base point and the other end of the linkage in a translational joint. I am trying to lock the base pivot, Joint 301001 for the initial motion and then release (Joint 301001 is a revolute joint)
