autodesk robot structural analysis professional 2015SP3 has stopped working

Hi all,

I am trying to run a modal analysis for a 12 storey complex using the block lanczos algorithm, but it crushes after runing the modes 

about 40, I know I need about 60modes to achieve the 90% of mass partificaiton.

I am  missing something?

Regards,

Patkson.

Hi,

there are some memory issues with Block Lanczos algorithm.

Please use Block subspace iteration method - as on the screen capture below.

Yh but I don't understand, "memory issue"‎??
I'm using a 16 gig ram core i7 Sony laptop. And besides I have run even much big models than this 12 storey, The  most recent one was ridge tower 21 residential and it worked fine.

 There has to be something else.. but I will try what you have suggested anyway.. thx
