chemistry convergence failures in newmole

[Gary J. Ferland]

the attached does not work on the trunk, with chemistry failures, so tried with newmole at r4117. it stops due to chemistry failures.

Fix formatting of ticket text

[rjrw]

Input file contains grid command, but bug is independent of grid. Could the input be updated to the specific case which fails, rather than wasting time for whoever picks it up? Thanks.

[Gary J. Ferland]

I have rerun at r4139

p1.in file in initial post was a grid run with different failures.

conv.in shows first failure modes, due to chemistry

non-grid run, 20 chem conv failures

[Gary J. Ferland]

the second sim did run with the same convergence failures, but no particle conservation assert, with the head of the newmole branch. this second sim suffered the same type of convergence failures and stopped for the same reason as conv.in

it would be reasonable to get conv.in to pass first, then run the p1 grid

[rjrw]

Conv1.in runs to completion (albeit very slowly) after r4331.

Chemistry convergence still poor on trunk & ots2 @r6416, move assignment to next release branch
