Dear all,
i encountered a error message claiming my integer stack memory is insufficient. What i don't understand is: i was running the simulation with 30000000+ elements without this error message, but after reducing the mesh to about 20000000+, and this error occurs. Does it indicate there's something wrong with my model please? Below is part of the monitor log where the error message is prompted: Slave: 4 Slave: 4 Slave: 4 +--------------------------------------------------------------------+ Slave: 4 | *** INSUFFICIENT MEMORY ALLOCATED *** | Slave: 4 | | Slave: 4 | ACTION REQUIRED : Increase the integer stack memory size. | Slave: 4 | | Slave: 4 | Details : | Slave: 4 | Requested space : 1258818 words | Slave: 4 | Current allocated space : 67888655 words | Slave: 4 | Current used space : 67734314 words | Slave: 4 | Current free space : 154341 words | Slave: 4 | Number of free areas : 2 | Slave: 4 +--------------------------------------------------------------------+ Slave: 4 Fatal error generated in gKSelEl Slave: 4 Message :- FULL : Failed to make a data area for KSelEl Slave: 4 gKSelEl called by :- gKVxEl_ZN Slave: 5 Slave: 6 Slave: 6 +--------------------------------------------------------------------+ Slave: 6 | *** INSUFFICIENT MEMORY ALLOCATED *** | Slave: 6 | | Slave: 6 | ACTION REQUIRED : Increase the integer stack memory size. | Slave: 6 | | Slave: 6 | Details : | Slave: 6 | Requested space : 13082585 words | Slave: 6 | Current allocated space : 69414234 words | Slave: 6 | Current used space : 58881147 words | Slave: 6 | Current free space : 10533087 words | Slave: 6 | Number of free areas : 2 | Slave: 6 +--------------------------------------------------------------------+ Slave: 6 Slave: 6 Slave: 6 Details of error:- Slave: 6 ---------------- Slave: 6 Error detected by routine MAKDAT Slave: 6 CDANAM = LCON CDTYPE = INTR ISIZE = 13082585 Slave: 6 CRESLT = FULL Slave: 6 Slave: 6 Current Directory : /FLOW/SOLVER/GLOBAL/MGRID/MGRID_TG2/ZIF20/CS Slave: 5 Slave: 5 +--------------------------------------------------------------------+ Slave: 5 | *** INSUFFICIENT MEMORY ALLOCATED *** | Slave: 5 | | Slave: 5 | ACTION REQUIRED : Increase the integer stack memory size. | Slave: 5 | | Slave: 5 | Details : | Slave: 5 | Requested space : 260760 words | Slave: 5 | Current allocated space : 73552708 words | Slave: 5 | Current used space : 73487421 words | Slave: 5 | Current free space : 65287 words | Slave: 5 | Number of free areas : 2 | Slave: 5 +--------------------------------------------------------------------+ Slave: 5 Fatal error generated in gKElSel Slave: 5 Message :- FULL : Failed to make a data area for KElSel Slave: 5 gKElSel called by :- gKSelEl Parallel run: Received message from slave ----------------------------------------- Slave partition : 4 Slave routine : ErrAction Master location : RCVBUF,MSGTAG=1032 Message label : 001100279 Message follows below - : +--------------------------------------------------------------------+ | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | Stopped in routine gKSelEl | | | | | | | | | | | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | An error has occurred in cfx5solve: | | | | The ANSYS CFX solver exited with return code 123.

You just need to make the integer stack bigger. Have a look in the documentation for how to do this.
