Thank you Carlos,

I tried and it works.

Dear F. Mc Kenna, I solved with my first model where I imposed a "pattern Plain". Now I changed the configuration of my beam from a cantilever beam to a simply supported beam. I fixed the displacement of the extreme nodes with the command (for 2D model): fix 1 1 1 1 fix 13 1 1 1 and after ...

No-linear model with rotational spring

Dr F. Mc Kenna, I am so sorry to bother you again for another problem. I built a model of simple supported beam with a zeroLength Element inside that model a rotazional spring. I imposed only a gravity load to perform the static analysis, but my model is very non-linear (the spring has a very low st...

Dear Frank Mc Kenna, I´m really sorry, but I must ask you again something because my code does not work. I tried to use the command suggested by you yesterday, but "timeSeries Path" does not work. So I put the time series inside the pattern Plain command and Opensees did not give me any er...

Dear Frank Mc Kenna, I´m sorry, but I need again your help. There are not examples about the "Plain load pattern" associated with a "Path Timeseries", so I tried to implement the procedure that you described, but without any success: where exactly I must insert the "series&q...

MultipleSupport Pattern

Dear Frank Mc Kenna, I implemented a code with a "MultipleSupport Pattern" using a acceleration series to define the "groundMotion". I did not specified the integrator in "groundMotion". I applied the excitation to a free node (last node) of my cantilever beam because t...

Coordinate systems

Hello Frank and Silvia, I'm quite confused about the coordinate system. I modeled a simple 2D cantilever beam with a rotational spring to simulate a fracture damage. My model with the global coordinate system is |_______@___________ | ^ | | Y |----------->X In manual at page 284 the local coordinate...
