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?
Solved! Go to Solution.
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:
