would have preferred having an .OPTION to select between Trap and Modified Trap.

Andy - Good point, there should be a .option to select modified trap.  We will add support for ".options method modtrap" in the next revision.

 

If that is done, it needs the complementary command as well -- something to force non-modified Trapezoidal.  Currently, ".options method=trap" gives you EITHER Trapezoidal or Modified Trap, whichever one had been selected already.  But it provides no way to change from Modified Trap to regular Trap.  You would need yet one more .OPTIONS choice.

 

The anti-trap ringing has caused a lot of confusion, as it is simply a post-processing that hides it from the user.  ...

 

It can.

 

On a personal note, the Help page that describes it (added after Mike Engelhardt moved on) was extremely helpful.  I am very grateful to whomever added that page.

 

I also never understood the change (circa 2019) to omit CERTAIN nodes from that post-processing when Modified Trap is selected.  IMO, if Modified Trap is used, it ought to be uniformly applied to ALL nodes, not just 95% of them.  (Perhaps it is worth revisiting that change?)
