Dear All, 
I have modeled Blast using the MMALE approach. Initially, the air domain is modeled as 64mm in size. It runs smoothly. Then I decreased the size to 10mm ,now it started showing an error as

 *** Error 70021 (OTH+21)
     Memory is set 28889386 words short
     memory size 1000000000
     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=####
My system has enough space. I don't seem to understand what is causing this error. Any help is greatly appreciated.

Hello,

LS-DYNA requires specification of memory size in the input command. Please see 'Execution Syntax' in Keyword User's Manual I.  The command that you are using is set to 1000000000 words of memory. Please increase that number by at least 28889386 to run your model. 

If you are using LS-Run to run your models please see below:

Dear Alex,
Thanks for replying.
I have already tried the method you have mentioned.
Even after adding the words short (28889386) to the memory size allotted (10^9) is still giving the same error with same digits of short word. As I came to know that the word limit (10^9) that I have provided is the maximum word limit of LSDYNA. Please correct me if I am wrong.
I tried to run the same model in different system with higher configuration but there also same error is showing.
I don't seem to understand where the problem is.
Any suggestion will be greatly appreciated

Thanks
