Hi MIRomero, Yes, I got this fixed in the source code I have and compiled it to an exe Do you have a copy of the source that you can compile? or are you using the executable files provided by the website? If you can modify the source and compile it, then you will need to do three modifications (like...

Hello Dr. McKenna, I think I found out how to correct this bug. It looks like it is better to avoid using resid vector for this method and use a local variable. I created a vector called allAccel and used it to store the accelerations. Also I have uncommented the two lines (981 and 982), that I had ...

Thanks Dr. McKenna for the reply. I posted a script previously here: http://opensees.berkeley.edu/community/viewtopic.php?f=2&t=61397 It is a modification of one of the shell dynamics examples but I added ground excitation to it. It assumes El Centro earthquake is in the ElCentroEQ.thf file (whi...

Hello Everyone, I was having problems running linear dynamic analysis when my Opensees model has shell elements with non-zero rho value and subjected to ground excitation. I decided to debug the code and ended up finding at least one bug. I am posting them here to see if someone else had similar pro...

Hello Everyone, I had some problems running linear dynamic analyses for Opensees models that contain shell elements. I was wondering if someone else had similar problem, and whether this a bug or a mistake in my models. Generally, If the model has shell elements with rho value defined and subjected ...
