emergency recovery of data files
|
Somtetimes, in the end of long run, FLUENT may fail to write the data file and give a "malloc" error. This can be due if, for example, one uses UDF and small "memory leakage" accumulates over time. In this case valuable data file which took a long effort to converge can be lost. 1. turn off some feature in the model to free some memory. This should be some passive scalar (radiation, for example), which does not affect the solution. 2. run one iteration. You may still have some errors here. Never mind that. 3. write the data file to a different name. Might as well save the casefile. 4. Read new case and data, turn the feature back on and run futher (you can switch off solution of other variables except this feature). |
