Another alternative is to increase the system's virtual memory (use the System icon in the Control

Panel on Windows).

Windows 32-bit systems are limited to a maximum work space or database size of around 2 GB;

however, in practice, you often get less than that (e.g., 1400-1500 MB) due to system DLLs fragment-

ing the memory address space available to ANSYS. This fragmentation decreases the size of the

biggest contiguous block of memory available to ANSYS. Thus, on Windows 32-bit systems, closing

other programs to increase the system virtual memory or increasing the system virtual memory

manually will not resolve this error. The only solution is to decrease the work space or database

size, or both.

The memory (-m) size requested cannot currently be addressed using dynamic memory mode.
ANSYS addressing can be changed by turning on fixed memory via the -f command line option.

This message may occur at startup.

Include the -f command line option on the program execution command to remedy the problem.

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

This model requires more scratch space than ANSYS can address in dynamic memory mode. ANSYS
addressing can be changed by turning on fixed memory via the -f command line option. Problem
terminated.

This message may occur while you are running ANSYS.

Include the -f command line option on the program execution command to remedy the problem.

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

This model requires more scratch space than available, currently XX words (YY MB).The scratch
space may be increased by increasing the work space, currently XX words (YY MB), via the ANSYS
command line memory option. Problem terminated.

This message may occur while you are running ANSYS.

If you are running the program in dynamic memory mode and the internal calculations that the

program is trying to perform cannot fit in the scrat ch space, the program will attempt to allocate

additional memory to meet the requirements. However, this message may still appear if:

• Some portions of the program cannot use the additional memory that was allocated or allocate the
  memory when it is needed. The processing that the program was trying to perform when this message
  appeared took place in one of these portions.


• You used the -f command line switch so that the program would use a fixed-mode memory addressing
  scheme. Thus, no dynamic memory allocation is allowed.

If you receive this message, specify a higher -m value on the program execution command or change

your -f command line option and execute the program again.
