Questions about ExaCA function in AdditiveFoam

[Liana-Quinn]

I tried to run AMB2018-02-B tutorial case with the ExaCA function. However, the error "Must provide path to input file on the command line." always popped. The input.json is readable according to the test. And I also put material data in the ExaCA folder. None of them helpful to solve the problem I encountered.
Just got puzzled. What is the expected output of ExaCA in AdditiveFOAM? Is it only the temperature.csv? Or this function enables us to run AdditiveFoam and ExaCA simultaneously?
BTW, the function line in AdditiveFOAM/tutorials/AMB2018-02-B/system/controlDict is empty. I'm not sure if ExaCA should be included in this function line.

@Liana-Quinn,

Thank you for your interest in using AdditiveFOAM! If the function line in controlDict is empty, the ExaCA Function Object will not run. This Function Object is responsible for interpolating and writing out the thermal histories needed by ExaCA.

I apologize that our webpage documentation has not been updated since the latest release. To run the tutorial with ExaCA, you should use the following command:

Allrun -withExaCA

You can verify this in the Allrun script, where this option enables the Function Object in controlDict: Allrun Script

If you continue to encounter issues after making this change, the error may be on the ExaCA side. Please provide the log files for both AdditiveFOAM and ExaCA so we can assist you further in debugging.

Thank you!

Thanks for your reply and suggestions. I tried all the steps you mentioned before asking this question. And source this function to ensure it's enabled. All these steps only enable me to use the ExaCA function and get temperature.csv. However, the parse error of json still pops up. The error message is attached. I also added material.json to AdditiveFOAM/tutorials/AMB2018-02-B/ExaCA folder, however, it didn't helpful to solve this issue.
record of error message.txt
The adjusted Allrun and log.AdditiveFOAM are both attached. From the log file of AdditiveFoam, nothing seems to be wrong.
Allrun.txt
log.additiveFoam.txt
For the log file for ExaCA, I couldn't find it after running the AMB2018-02-B.
The other thing I don't understand besides solidification data is what else I can get with the ExaCA function? Does it enable me to run ExaCA simultaneously or just get the thermal profile as the input for ExaCA?

It looks like there may be a typo in the Allrun.txt file - ExaCA does not take a -i flag on the command line, the input file argument directly follows the executable (see https://github.com/LLNL/ExaCA/blob/master/README.md for examples).

@Liana-Quinn - It looks AdditiveFOAM and the ExaCA Function Object ran fine (according to the log.additiveFoam file). The issue appears to be when running the ExaCA executable itself. ExaCA is a cellular-automata code for predicting the explicit solidification structure, in this case, using the solidification data from AdditiveFOAM. @MattRolchigo, can you look at the log file to see why there is a parsing error?
