Please let me know

 

How to increse itterative solver memory in NX  nastran 7.5?

 

This is because, there was an error message"the output file is in wrong format", whenever

the number of element were increased.

 

And the sim1-solution_1.f04 shows the message that "the itterative solver memory is to be increased"

Dear Muralidhar,

Simply click in EDIT SOLVER PARAMETERS in your study and in the field MEMORY you can specify the RAM allocated during the solve. Note that Nastran allocates all specified memory to the solver during a solve, which could affect other processes you want to run simultaneously.

 

You must include the unit of measure with the value. For example, for 500 megabytes, enter 500Mb (no space between the value and the unit of measure). For 10 gigabytes, enter 10Gb.

But also I suggest to take a look to the *.F06 file located in the SIMulation directory and search for the word FATAL, you will see there the exact source of the error. Also the LOG file provides interesting info.

Best regards,

Blas.
