Report Unique IJK Tuples for Failed Bubble/Dew Point Calculations
This commit switches the debug file's records of "failed" bubble and dew point pressure calculations from a non-unique list of linearised Cartesian indices to a unique list of (1-based) (I,J,K) tuples. This format is hopefully easier to read for humans. Thanks to [at]blattms for suggesting the gatherv() helper function which greatly simplifies the communication pattern. Example from selected time steps in a real field case with Cartesian dimensions 137-by-236-by-58: - Original Finding the dew point pressure failed for 2 cells [1467066, 1467066] Finding the dew point pressure failed for 8 cells [1467063, 1467063, 1467066, 1467066, 1467066, 1467066, 1467066, 1467066] - This commit Finding the dew point pressure failed for 1 cell [(71,89,46)] Finding the dew point pressure failed for 2 cells [(68,89,46), (71,89,46)]
