Re: PressureDependMultiYield Class

I am also confused with the two lines 2092 and 2094 in PressureDependMultiYield.C It seems there is a bug here ... two if(X < 1.) blocks, a return happens in execution instead of issuing an error. Can you please advice! 02091 if ( fabs(X-1.) < LOW_LIMIT ) X = 1.; 02092 if (X < 1.) return; 02093 0209...

PressureDependMultiYield Class

Hi all, I have a question about the variables "hv" and "pv" located in the constructor of the PressureDependMultiYield Class. The two variables are assigned to two other variables Hvx and Pvx. What do they mean? Checking the command manual for the "nDMaterial PressureDependMultiYield" they are not d...

static double* residualPressx; in PressureDependMultiYield.h

Hi,

Inside the header file: PressureDependMultiYield.h

there is a declaration

static double* residualPressx;

I do not really know what residual pressure means in here?? Any ideas are welcome.

Thanks

Re: Compilation Error on Debian 6.02 (Squeeze)

That file actually works for Ubuntu 10.10 .... for sequential OpenSees only though. I'm not familiar with the Makefile utility. OpenSees was my first encounter with it. I know that OpenSees is built for various Linux clusters in CA. Nevertheless, the OpenSees team does not share clear instructions o...

Re: “Pseudo-dynamic Analyses”experiments in OpenSees ?

The "0.1"is a factor to be multiplied by the values vector ... so it is arbitrary. For more than one node (using the same MySeries) you just add another sp command to the pattern. pattern Plain 1 $MySeries { sp 58 1 0.1 sp 102 1 0.1 sp 107 2 0.2 sp .. . } If you need different time series for each n...

Re: “Pseudo-dynamic Analyses”experiments in OpenSees ?

First you'll need to define a time series (pdf manual page 304): Series -time {list_of_times} -values {list_of_values} or via files: Series -fileTime $fileName1 -filePath $fileName2 The sp command (page 307) sp $nodeTag $DOFtag $DOFvalue The pattern command (page 305) pattern Plain $patternTag (Time...

Re: “Pseudo-dynamic Analyses”experiments in OpenSees ?

I was not able to open the paper but I guess your model can be implemented in OpenSees. You need to define an SP constraint to the node attached to the jack. The SP constrains should be introduced via a pattern command and a time series command (look up manual) Also, I guess this is a .exe user ques...

Re: Compilation Error on Debian 6.02 (Squeeze)

Please share the Makefile.def if you were able to build it (and list needed libraries please). The forum here seems to have something against Linux builds :( Try this Makefile.def https://docs.google.com/document/d/18llWrLqu42ruQonOQGwqBZMbl2m7hMQovUjt6563quc/edit?hl=en_US&authkey=CMfcybIK The probl...
