SSI for GSA and Galapagos error

Hi everyone,

I've been experimenting with Galapagos for the past few weeks, and been running into some problems with the evolutionary solver. I'm wondering if anyone has the same problems. Could someone test my setup and let me know if it works fine at your end?

What happens is this:

For a few minutes, the evolutionary solver performs well. After that, an error occurs, and the solver cannot continue (see attached screenshot).

Then Rhino states this error message:

Request for generated beam has coincident node points and is ignored
The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

I've included the model I used to test Galapagos. Is is a very simple planar suspension bridge with two masts.

Help is very much appreciated!
