Thank you sir, I found the error. but again it is showing this warning- WARNING TwoNodeLink::setup() - element: 40 ignoring nodes and using specified local x vector to determine orientation. It's a 3-D model I am working in X-Z plane and the link is between nodes parallel to z axis. In that case my ...

My opensees.exe gets vanished in a flash (unable to see any errors) when I create a twoNodeLink element

Can anyone kindly help me!
