Human Femur Modal analysis using ANSYS program

Hello
my name is Hani

my thesis is about to calculate natural ferquencies and modal shape to
the Human Femur using ANSYS program ver.10.
i had completed the meshing process. after meshing the femur size was
206 Mb mega byte .
when i start in solution stage and when i complet the boundry
condition for my problem , and when i give solve order and in any way
of solution ways like Block lanzos , Supspace, ....or REDUCED METHOD.
after about one or two mint i get Fatal error message in ansys :
this modal requires more scratch space thanavailable, currently
244887881 w0rds(934mb) ansys was not able to locate more nmemory to
proceed please shut down the applications that my be running or icreas
the virtual memory on your system and rerun ansys.problem terminated .

Knowing that my computer Ram 2048 mb , and i am also had added large
size from my hard to be as Ram .

please any imprtant tips i will be grateful
THanks to all those like to help humans
Special thank to Mr. Dave Parker for his last helping

 

How many DOF do you have? You need just enough to capture the highest
mode shape you can expect.

Use a hex mesh to reduce the DOF of the model (my personal favorite).

Search the newsgroup for 3GB switch.

Check the ANSYS documentation for allocation of file space for large
jobs.
