Where do I find the subDMAP files and documents to aid in alter creation?

Stumpy 3 months ago

I recently had a question from a co-worker about getting progress feedback during a SOL 109 run. I thought it would a simple matter of finding the file in <Nastran Installation Location>\nast\del, finding the right subDMAP and adding a MESSAGE command. The reference guide shows I need SEDTRAN->TRD1->DTRANRS. I found sedtran.dmap and calls to TRD1 within but at that point the trail got cold. I can't find the file that has either TRD1 or DTRANRS.

The DMAP programmer's guide has an entry for TRD1 but not DTRANRS. Is custom dmap alter at that level even possible?

Similarly I have seen people make use of things like SELG, but again, I can't find the documentation to let me know what the inputs/outputs are.

You can use compile statement to list down the complete flow of subdmap sedtran like below:

SOL 109 $ direct Transient Response
compile sedtran list$

CEND

This will print the subdmap statement in f06 file

Thank you. I ran this and it dumped the contents of sedtran.dmap to the f06. It doesn't contain the more detailed information for TRD1 or DTRANRS. Is there a way to go deeper?

TRD1 do exist in dmap guide:

I suspect Dtranrs is same as sedtran ; note that this is the main subdmap for the direct transient response analysis
