Dear Seismosoft,
I'm trying to make an eigenvalue analysis but when I run the model, Seismostruct gives an error message : " Maximum size of the array ClassPnt exceeded. Analysis interrupted."
Is it because the modelling is too large to run on a PC with 4 GB of RAM or because I have a lot of element classes in my model? There is no limit on the number of element classes?
Thank you for your attention.

Dear dpucci,

The error message is related to program's memory limits. In the upcoming version 7 the memory limits of the program have been increased.
