1.st commit Elastic Modulus Connection

[japaf]

Why is diffusivity.py being deleted? Is it an oversight or is there some reason behind it?

[symphoton]

I already mailed Sigve that something got mixed up with the commits. It's definitely not about the forward mapping model for the elastic modulus... And it seems to break my workflow :-(

[sigveka]

It may come from my end, however, I merged GitHub "nextRelease" into my before I made my commit, I shall have a look.

Sorry about that, I am not sure why the ".py" file was deleted from my repo, the directory was there.

@japaf/MWBASF: Is this request clean to be merged now?

[sigveka]

I just tried foamExpansion (with 0D workflow), foamAging is still running.

@Pavel

• Am I right in saying that “initModels2” in foamExpansion redundant?
• Once up on a time I made an initialisation strategy for “ForwardMappingModels”, initialising the parameters using simulations I/O data, is this what you are doing in “initBubbleGrowth”?

foamExpansion workflows run for me. So no objections from my side to merge it.

[japaf]

Both foamExpansion and foamAging run OK for me, so no objections against merging.

• We created "initModels2" with Mohsen at the time when initialization of Rheology was sometimes ending prematurely with segmentation fault, so we wanted it isolate it a bit. If everyone can initialize Rheology without problems now, we can merge "initModels1" and "initModels2" into one script.
• What I am doing in "initBubbleGrowth" is basically running the detailed model once, reading all the outputs, fitting the surrogate model to the results and more or less manually creating the model in the database. I know that you were helping me to use the fitting procedure from the framework. But if I remember correctly, it was loading the data one by one into the database. So, it created something like 200 launcher folders during the fitting, which was both slow and messy. Thus, I am not using the framework for the fitting. But it is a long time, so I may be wrong.

[sigveka]

I could run the workflow after only running initModels1 you see (and some of the updates to the database that are done in initModels2 are default in those surrogate models)

I believe I can fix the 200 launch folders issue for you, is it desirable?

• initModels2 initializes polymerViscosity, surfaceTension, Rheology and Rheology_Arrhenius. I think that with default inputs only polymerViscosity is used. Also, that one can be initialized automatically without problem, I think. So if you didn't run the initModels2, you would get into problems only if you enabled surfaceTension or Rheology in the inputs. My opinion is to merge initModels1 and initModels2. The current state is perhaps more confusing than helpful.
• The thing is, my current approach works at this moment. If you fix the issue, we would be perhaps more consistent with other init scripts, but it would not bring any new functionality. So you must decide if simplifying the initBubbleGrowth is worth your time.
