Re: Questions about RemoveRecorder class

I read the example: Infill Wall Model and Element Removal (http://opensees.berkeley.edu/wiki/index.php Infill_Wall_Model_and_Element_Removal#Implementation_of_Infill_Wall_Removal_in_OpenSees). Please take care of the following paragraph: A progressive collapse algorithm is developed [4-6], the diffe...

Re: stop the analysis, modify the model, restart the analysi

I think I've gotten some misunderstanding or made some mistake, so I wasn't able to solve my problem. Would you like to give me a example and show me much more details about the loop. :P
Thank you very much!

Dear vesna, Thanks for your reply.

Re: We are collecting OPENSEES User-Requirements Data

Dear Silvia, There are many posts mentioned how to spit mass,stiffness and damping Matrix out. At present neither mass or modal participation factors can not be recorded with OpenSees. Although We can go to the source code, find it and spit it out, it is very difficult for us. Would you please do so...
