The last error message was "Analysis: Time step too small; initial timepoint: trouble with u3:40ua-instance j:u3:12" I tried the following as it was recommended on a forum But now I'm not getting the desired results. My circuit is shown below, it is a biasing circuit of an RF ...
Time step too small; initial timepoint: trouble with node "u1:21"add the UIC option to skip finding the initial operating point, and you get: Code: [Select]Time step too small; initial timepoint: trouble with node "u1:30"which IMHO indicates something iffy about either the model's ...

But if the course material or university doesn't use those 'better' tools , then that's a moot point. Now I still want to add that an i9 will run LTspice marginally faster than say an i5. Even if the workload maxes out at a handful of threads.. its very likely such chip has ...
The "time step too small" error normally comes about because you have something that is trying to change too fast, possibly while trying to solve for the initial operating point for the simulation. I can't tell which device D1 is because you aren't consistent in your reference designations...
