ST_Malloc: out of memory.malloc_storage...!
 
The exact error is as follows..

Warning:ST_Malloc: out of memory.malloc_storage: uanble to malloc id, size 5586384, t 19, myid 1000000.

Error: FLUENT received fatal signal (ACCESS_VIOLATION) 1. Note exact events leading to error. 2. Save case/data under new name. 3. Exit program and restart to continue. 4. Report error to your distributor. Error Object: ()

Even I tried to save it under new name...but failed each time...n I am having enough free space on my disk..so no problem with that ...I am not getting why this error is there...!

this error is mainly due to the insufficient system memory or very high magnitude in boundary condition which could not be calculated by the processor
