Error occured when run with spotting model #54

Closed yqin123 closed 7 months ago

yqin123 commented 9 months ago

Hi Chris,

I updated the spotting model on my end and tried incorporating the HRR_transient into it.

However, when I run a test case with the Eulerian spotting model activated (using the command elmfire elmfire.data), it shows "segmentation fault ..." while outputting results. The results are correct regardless.

Meanwhile, when I run the case using the command elmfire_debug elmfire.data, it informs me something went wrong with lines 5 and 58 in "elmfire.f90" (suggesting: "Floating-point exception - erroneous arithmetic operation."), without outputting any results.

This problem only occurs when I run with my spotting model.

Could you please help me check it out or give me some suggestions on finding out what is wrong? I have attached the test version of ELMFIRE and my test input files here. Please let me know if you need any further clarification. elmfire_public-UMD_SPOTTING_MODEL.zip spotting-test-inputs.zip

Thanks, Yiren

Thank you, Yiren - confirming receipt. I will take a look! I could probably figure this out by diffing the source code, but is the source in the archive elmfire_public-UMD_SPOTTING_MODEL.zip a local fork / test version that you have created yourself, i.e. it's not in the public repo? Thanks!

yqin123 commented 9 months ago

Hi Chris, Thanks for your help! elmfire_public-UMD_SPOTTING_MODEL.zip is a local branch but is modified based on the most recent public version (my fork was updated days ago).

Thank you, Yiren. A diagnostic array was being allocated only when RANDOM_IGNITIONS=.TRUE. but it should be allocated for all cases. Commit https://github.com/lautenberger/elmfire/commit/7aeea6a7ec528a87a77581145095334d2e3bb2b2 resolves this issue. Basically, in elmfire.f90 delete line 270 and at line 271 add this line:

IF (MODE .NE. 2 .AND. NUM_MONTE_CARLO_VARIABLES .GT. 0) ALLOCATE(COEFFS_UNSCALED_BY_CASE(1:NUM_CASES_TOTAL,1:NUM_MONTE_CARLO_VARIABLES))

I think this will resolve your issue but if not let me know. Thanks for the report!

Hi Chris, Thank you very much! I modified the lines you mentioned, and now it works with elmfire elmfire.data, however, still shows errors when I am running elmfire_debug elmfire.data. This problem can be reproduced using the updated version, even without activating spotting on my end.

Could there be some problem related to the compilation? Let me know if you need other information. Thanks for your help again!

yqin123 commented 9 months ago

Hi Chris,

It has proved to be a compilation problem on the server here at UMD. I tested on another Linux machine, both commands work well now. I made a pull request later with some modifications and included detailed descriptions there.

I will leave this issue open and see whether the compilation problem can be resolved.

lautenberger commented 9 months ago

Hmmm, that is quite strange. Could you try running ELMFIRE's debug executable to see if it gives a line number where the erroneous arithmetic operation is occurring?

yqin123 commented 9 months ago

I recently tried to run the debug executable without an input file, it showed the error occurred at lines 58 and 5 in file elmfire.f90:

#40  0x4c6eb0 in elmfire
    at ../../source/elmfire.f90:58
#41  0x4d988f in main

Hi @yqin123 - just confirming that this issue has been resolved with the change in compiler flags that we figure out earlier this week?

yqin123 commented 7 months ago

Yes, Thank you very much! @lautenberger
