dear All,
I am now running Fluent with specifying those parameters via Matlab. Results are extracted using UDF from Fluent and then processed by Matlab to decide whether additional simulation should be executed. The iteration calculation is controlled via the command of
case 1
iFluentTuiInterpreter.doMenuCommandToString('solve set number-of-time-steps 200');
iFluentTuiInterpreter.doMenuCommandToString('solve dual-time-iterate');
or
iFluentTuiInterpreter.doMenuCommandToString('solve iterate');
case 2
iFluentTuiInterpreter.doMenuCommandToString('solve dual-time-iterate 200 200');

generally, it works well. But, while the multiple of Time-step used in Autosave and Time-step specified in the Calculate panel are coincidentally equal (for example, per 100 timesteps for autosaving and 200 timesteps for calculation), Fluent would crash at the end of the last iteration with following Error Information

No error handler available

Error: Cortex received a fatal signal (SEGMENTATION VIOLATION).
Error Object: ()

can anybody help? many thanks
