Hi~ I analyzed a soil structure interaction model with OpenSees. I used a rayleigh damping. The manual says " This command is used to assign damping to all previously-defined elements and nodes " Q1. Because I have two materials; steel and soil. I have to apply another damping ratio to eac...

Hellow.. I compiled the OS ver 1.7.5 with Mumps solver. So, I tested it with a parallel example tcl script (ex4.tcl) like below.. # --------------------------------------------------------------- set pid [getPID] set np [getNP] if {$np != 2} { puts "ONLY WORKS FOR 2 PROCESSORS" exit } mode...

I complied the OpenSees ver. 1.7.5 to a parallel machine of my univ. So, It works with OpenSees Multiple interpreter. thanks by the way I have some questions 1. I used the analysis system, ParallelProfileSPD. but because my model is big(over 2000 elements for a processor), it takes much time to anal...

Hi~ I have studied about soil structure interaction. Bayram said that OpenSees Ver 1.7.5-beta works well. whereas ver 1.7.5 is not good. So, I'd like to use the version 1.7.5-beta.. But I can't find the version. How could I get it? Or I downloaded the 1.7.5 in CVS. How could I figure out the version...

Hi~

I saw your other posts..
And I have same problems... like "update material.."

By the way you said that ver. 1.7.5 beta was fine.

How do you get the ver. 1.7.5 beta??
I'd like to test my SSI model with the version.

Thanks,

DK

I have tried to install OpenSees to a supercom of my univ. I installed OpenSees ver1.7.5 with Unix version. Are there many differences between ver 1.7.5 and ver 2.0? If it is or I have to use it, I'd like to use ver. 2.0.... but I could not find OpenSee ver2.0 for Unix.. 1. How could I use it with L...

Hellow.. I’m a graduate student in South Korea. I saw a PDF file about OpenSees parallel interpreters. http://it.nees.org/documentation/pdf/TN-2007-16_McKenna-OpenSees.pdf It says that there are two interpreters. Because my simulation is a very large model. ( number of element : 110,000) I had thoug...

Hi~

I did some eigenvalue analysises a few month ago.

and I did same analysises for same models again yesterday.

But, the results were different from formal results.

Why is this happend?

I tried some methods. but I couldn't fix it.

could you help me? ^^;;;;

Hi~ I'm a graduate student in SNU, Korea. I have researched about soil-structure interaction... By the way, It takes too much time to analyze it. so I complied the OpenSees program(ver 1.7.1) to a MPI machine in my univ. It works in serial processing. But It does not run in parallel processing. Do I...
