Autodesk Robot Structural Analysis

[#1]

Hello, i've been using RSAP 2011 and after new install of 2012 version i get this message, when i try to calculate model.

It's the same problem when i create a new model.

But when i try small structural frame or meshed object (small number of calculation nodes) everything works fine.

Maybe this is licensing problem?

any ideas?

Hi

It is

THE SPARSE SOLVER ERRORS :  3300  Open file error   -> problem with opening temporary file

Clear windows %temp%   folder and \ or use different solver (multithreaded, iterative for large models)

Oh, thanks, changing the solving method worked !

Maybe there's some information about those solving methods, their field of uses and differences? It would be great to know more about the "brains" of RSA:

Frontal
Skyline
Sparse
Sparse M
Iterative
Multi-threaded solver
