Hi everyone, Does anyone experienced an "out of memory" issue while performing a series of sequential (not the parallel verions of OpenSees) transient analyses. I think this is a memory leak problem associated with recorder command. I have recieved the error when I re-run the same frame mo...

Hi to all,

I appreciate any means of information on compiling opensees 1.7.5 on mac osx v10.5.1.

Thanks in advance.

Silvia, Thank you for your fast response. From your reply I can see that there is no implemented record command argument which monitors only plastic state curvature (or full curvature output from "deformation" flag). Integration may be a good approach, however, it seems that it is not feas...

Hi Silvia, It is a well known property of opensees that you can easily monitor curvature at a section designated at integration point of a forcebeamcolumn element, in addition, plastic deformation at the ends in terms of rotation. However, it is not possible to relate "plasticDeformation (outpu...

Happy thanksgiving.

Silvia, It was a simple moment curvature analysis of a rectangle section. But, I think I have figured out the problem. Changing script into following form solved the problem. In other words omitting section number is a "must". previously: recorder Element -file Out/StressStrain.txt -ele 1 ...

Silvia, I cannot monitor stress-strain response of a zeroLengthSection element. I get a blank screen (no output) while performing a simple moment-curvature analysis. The script is based on opensees manual's script util. lib. Is there a limitation for this element type or am I doing something wrong? ...

Hi to all, I wonder if anyone uses print command. Recently I have noticed a slight change/bug in v1.7.4. Previous versions allow getting a hardcopy with specifying a filename, however, I can not do it with v1.7.4 (print filename.txt -node 22 -> does not work!). Is the syntax/code intact ? Any change...

Silvia,
Any news? (Otherwise I have to modify 240 records)
Best regards.

Silvia, According to changelog of v1.7.4, this version has the ability to read records directly from PEER strong motion database. However, I could not find any related how2 documentation (board & googled it). I have tried it via Path cmd, yet it reads file only when the commentary lines are dele...

Beyhan, Try to convert or trim the L shape into an I shape and recheck your results for the elastic response (in terms of Ix, Iy). Secondly, I strongly recommend you to check XSection's default coordinate system, which is different than regular cartesian. Regards. Note: Refer to "Quadrilateral ...

Dear all, First of all I would like to thank to people who kindly responded quickly to this very subject. Alisa wrote that "The best thing is not to use == with floating points. It is better to decide on some tolerance (e.g. +/- .00000001 )". I think this comment is very important and usef...

Dear Silvia, I have already mailed to "Tcl People". I do know that it is beyond opensees subject but may you please briefly explain what you mean by "you should never compare integer equality". How can I establish a condtitional statement comparing two double/float variables ? Al...

Dear all, I have discovered this problem while I was writing a parametric problem in Tcl for an opensees model. There are three scripts listed below, which MUST give the same results??? I simply add and subtract a number and compare with another variable that holds the SAME number. Code1: set a [exp...

Hi,
I would be very glad if you post the ftp address or other means in order to download the latest source code.
Note: I couldnot download files from http://opensees.berkeley.edu/cgi-bin/cv ... nSees/SRC/
neighter could I access CVS !

Thanks.
