erro memory ansys/lsdyna 12.0

[jmf20010]

Hi,my name is jorge
I m doing a simulation of collision ship in ansys/lsdyna 12.0
my computer is window 7 of 24 Gb of memory and two proce. of 2,6 Ghz
my problem is :
*** Error Memory is set 142379 words short
Current memory size 20000000
Increase the memory size by one of the following
where #### is the number of words requested:
1) On the command line set - memory=####
2) In the input file define memory with *KEYWORD
i.e., *KEYWORD #### or *KEYWORD memory=####
when run o file

help me ,what is a solution???
thanks for the answer

This is an easy one. Your analysis terminates with an error because you do not have enough RAM specified to run your job. You can specify RAM (upper limit to allocate) in a number of ways. I am not totally familiar with the ANSYS/LS-DYNA syntax, but in an LS-DYNA input deck at the very top there is a *KEYWORD card you can use for this. For example:

*KEYWORD 20000000

will allocate 20000000 WORDS of memory size.

Similarly, you can specify this directly on the command line when you run the job:

lsdynasolvername.exe i=inputdeck.k memory=20000000

where lsdynasolvername.exe is lsdyna970.exe for example. This is the best way to run the job.

You will need to allocate at least 20142379 WORDS for your job to run, I would recommend using at least 30000000.
