21.5. Understanding Memory Err or Messages

This model requires more scratch space than available. ANSYS has currently allocated YY MB and
was not able to allocate enough additional memory in order to proceed. Please increase the vir-
tual memory on your system, and/or increase the work space memory and rerun ANSYS. Problem
terminated.

(Sparse or Block Lanczos solvers only):There is not enough memory for the <Sparse or Block
Lanczos> solver to proceed. Please increase the virtual memory on your system and/or increase
the work space memory and re-run ANSYS. Memory currently allocated for the <Sparse or
Block Lanczos> solver = YY MB.

(Sparse or Block Lanczos solvers only):There is not enough memory for the <Sparse or Block
Lanczos> solver to proceed. Please increase the virtual memory on your system and/or increase
the work space memory and re-run ANSYS. Memory currently allocated for the <Sparse or
Block Lanczos> solver = YY MB. Memory currently required for the <Sparse or Block
Lanczos> solver to continue = YYY MB.

(Distributed Sparse solver only):There is not enough memory for the Distributed Sparse solver
to proceed. Please increase the virtual memory on your system and/or increase the work space
memory and re-run ANSYS. Memory currently allocated by ANSYS = YY MB. Memory allocation
attempted = YYY MB. Largest block of ANSYS memory available for the Distributed Sparse solver
= YYYY MB.

The messages listed above may occur while you are running ANSYS.

This type of message appears when you are running the program in dynamic memory mode and

the program has attempted to allocate additional memory, but it failed because it could not find a

large enough contiguous block of memory to proceed.

On either 32-bit or 64-bit systems, specifying a higher -m value on the program execution command

and executing the program again may help. However, if a large enough block of memory is still

unavailable, changing the -m value will not help. You can also try decreasing the database size to

help free up more work space, allowing you to continue with the analysis. On 64-bit systems, in-

creasing the system virtual memory may help. Try increasing the system virtual memory so that the

physical memory (i.e., RAM) plus the virtual memory comfortably exceeds the memory available at

the failure point (shown in the error message).

For more information, see Memory Management and Configuration in the Basic Analysis Guide.

The memory (-m) size requested is not currently available. Reenter ANSYS command line with
less memory requested.

The database (-db) space requested is not currently available. Reenter ANSYS command line with
less database space requested.

Either of these messages may occur at program startup.

The memory used by the program resides within the system virtual memory. The required system

virtual memory for the amount of memory that you requested for either the work space (-m) or

database space (-db) for the program (via either the program command line or the configuration

file) is not currently available. Request less work space or database space if possible and execute

the program again. If the initial requested memory is required, then wait until sufficient system

virtual memory is free and try again.
