Hi,

I have a following issue: I would like to set homotopy order in a dc simulation using OCEAN script. I found in manuals that:

You can specify methods and their orders by specifying a vector setting such as homotopy=[source ptran gmin].
Possible values are none, gmin, source, dptran, ptran, arclength, tranrampup, and all.

In OCEAN script I can run DC simulation with a homotopy method as follows:

analysis('dc ?dev "/voltage_dc_source" ?param "dc" ?start "low" ?stop "high" ?step "1m" ?homotopy "dptran" )


However, is it possible to define more than one homotopy value? I cannot find any scenario that works.
 

You probably already tried such syntax versions for the continuation methods:

 

I think I tried one or two of the above. So not all of them. I will check them tomorrow and give a feedback.

I used ADE L GUI to see how homotopy is chosen there. It is possible to choose only one method.
