Bug in onec: it fails to refresh the network (NT) admittance data across multiple execute (XQ) blocks in a multi-case deck.

Hi Maury,

I noticed a large discrepancy between the results from cocoaNEC2 and onec. Claude looked at both output files and thinks it found the problem. The conversation with Claude is here: https://claude.ai/share/c15e4119-d034-44a9-b04c-824d8f130647

I hope you choose to fix it. I love how fast it runs and I am preparing to do a lot of antenna optimization work very soon.

Thank you.

Hey Gene, do you mind uploading the .nec deck in question? Or are you using one of cocoaNEC's internal formats like .nc?

Hi Maury, CocoaNEC can export a deck. I have attached it. Gene

Hi Maury, How's it going? Any update? Do you need anything from me? Thanks! Gene Risi

All is good and I think I have a fix. But I'm on the road for the next few days and away from my dev machine so I won't be able to do a build until I get back - sometime on the weekend.

[maurymarkowitz]

Hey Gene, do you mind sending me the .out file from your existing NEC engine for this file? I have some new code in which may be a fix, but I'd like to have it match your output line-for line. You can email it to me if it's too large to post here, but I think it should upload OK if you zip it.

[w1ebr]

I will try to attach the two zip files here:

They won't match line for line - I noticed slight differences in the calculations when using onec for a single frequency.

cocoanec2.internal.zip

cocoanec2.onec.zip

[w1ebr]

Hi Maury,I uploaded both output files. I don’t expect a line for line match but I can either input both of them into the visualization portion of cocoanec2 or have an AI do a smart comparison.GeneOn Jul 18, 2026, at 7:56 AM, Maury Markowitz ***@***.***> wrote:maurymarkowitz left a comment (maurymarkowitz/OpenNEC#10) Hey Gene, do you mind sending me the .out file from your existing NEC engine for this file?

Ok, some progress, perhaps enough. I do think this opened a new can of worms that I am going to have to look at more deeply at some point. Try 2.2.1b1 (in Releases) and let me know if it helps at all.

[w1ebr]

Hi Maury, Did you change the title lines at the top to say NUMERICAL ELECTROMAGNETICS CODE (onec 2.2.1) ? It looks like you might have left the version number the same? I am asking because it doesn't seem to be working and I want to be sure I have the right binary. (onec-macos-arm64-accelerate.zip) Gene .

Yes, I didn't change the version number for the beta.

I'm wondering if this is a Gatekeeper issue. Navigate to the folder where you installed it using Terminal and then do:

xattr -d com.apple.quarantine onec

And then try again. If that solves it I'll update the documentation. I guess I'll also have to do some code signing.

[w1ebr]

HI Maury,I had to do that to be able to run the one I downloaded, so, no, it isn’t working. I saw somewhere online that another version of nec2 has what might be the same issue so you might be dealing with a bug in the original source code.GeneOn Jul 22, 2026, at 9:08 AM, Maury Markowitz ***@***.***> wrote:maurymarkowitz left a comment (maurymarkowitz/OpenNEC#10) Yes, I didn't change the version number for the beta.
