TH2M constitutive relations refactoring
Continuation of the epic sequence !4951 (merged) !4960 (merged) !4969 (merged) !4976 (merged)
Runtime has improved. Compared to the state before the aforementioned MRs (fd0b1ae7) the heatpipe-rough ctest improved from 113.100 +- 0.114s to 96.486 +- 0.277s, around 14%. Half of the improvement comes from the last commit "[PL/TH2M] Extract Bu^TmN and N^T*N products"; here the runtime is 105.528 +- 0.229s.
Compilation times (recompilation of libTH2M.so only) improved as well:
| user | system | total | |
|---|---|---|---|
| before changes (fd0b1ae7) | 294.80s user | 7.30s system | 132% cpu 3:48.46 total |
| Extract ... products | 278.01s user | 8.96s system | 191% cpu 2:30.24 total |
| this MR | 267.69s user | 9.00s system | 199% cpu 2:18.53 total |
Almost no memory consumption changes are observable in the heatpipe-rough ctest. Very small increase in number of allocations, in evaluation of MPL properties (less than 0.02%).
