Simscape: Linear transformer open circuit error

Hello,
I'm trying to model a full-bridge DC-DC converter in simscape. I have the model built using ideal switches for the mosfets with a simple switching scheme. However, when I run the model, even though the simulation time is 0.05s it comes up with an error that at t=8s, the linear transformer is "open-circuited" because a couple switches are off simultaneously. This off-time should happen and is normal for the switching scheme.
I've attached a couple pictures of my diagram and error.

Would this error be because of no anti-parallel diodes with the switches?
Thanks!

Hello Ryan,
yes, you can create circuits that our tool cannot simulate with this topology. If you include things like diodes and snubbers, this can solve the problem.
Regards,
Joel
