LTspice simulation of inverter just stops working

[Flyback]

Hi,
Do you know why the attached LTspice sim just stops working at about 56ms?

Hi,

Because it's your design?

Look at U11 and U12. There's no connection to the first and last pins.

Why all those -5V supplies rather than just one? Why 2 x 10uH inductors in series at the output rather than one 20uH inductor? Unnecessary components and circuit nodes will slow down the simulation.
Reducing the number of RC filter stages at the input gets the sim to run past the 56mS point.
Like Lightium, I found missing pin connections. Perhaps the IC model asy files you use are not the same ones as I use. Analog Devices may have updated them?

Thanks, i fixed it up now, but its extremely slow, .any tips on speeding this particular sim up appreciated?

Divide it into modules and sim each module separately. That should identify which module is causing LTS to struggle.

Hey, do you have all the necessary literature regarding this file and inverter
or any kind of report you might have made along with this.
Kindly upload that

Thanks, but as you know, its not that great, its missing the control loop.....the one that regulates the current

hey , listen
iam in desperate need of a good project in ltspice
can you help me with the files if you have any
it would be really helpful
Kindly help in this regard

Any decent project (not too complex) would do.But, it would be nice if it has a practical application

This is a little noise maker. It's not perfect, but works.
