New ion species

SPIS
1

Hi all,

I am new to SPIS and am trying to simulate a complex plasma. After extensive manual and forum browsing, my understanding is that ion species may be simply typed in by their chemical formulas (taking advantage of Chemical Formula Parser) - is this correct?

I found the parser in the source code and there is exactly ONE post about it on the forums (from 2018) mentioning that hard coded species “will soon disappear” - but there is no mention of this in the manuals.

To give some context, I want to add custom ions like HCNH+, CN- and some charged dust substitute like C60-.

Thanks,
Oleg

Question resolved, the sim initialization log lists the created particles, their mass and charge and the custom species work!

Thanks for testing “unusual” (at least for us) chemical species and reporting the (positive) results.
It is also good to know that some features work as they should, even in configurations that have not been tested!
Best Regards,
Sébastien
