Hi,vesna, I need to write almost 1000 *.txt file in one txt file. for example, This is my record in :!: Periods%i.txt :!: but if I calculate 1000 times,there will have 1000 periods.txt and now i need only one periods.txt and all 1000 results in it. FOR EXAMPLE : T1 T2 T3 1 0.4 0.5 2 3 4 ....... HOW ...

Hi,vesna,
Thank you very much!

Hi,vesna, other question! set T1 [expr 2.0*$pi/$w1]; # 1st mod set T2 [expr 2.0*$pi/$w2]; # 2nd mod set T3 [expr 2.0*$pi/$w3]; # 3nd mod puts "T1 = $T1 s"; # display the puts "T2 = $T2 s"; # display the puts "T3 = $T3 s" # write the output file cosisting of periods :?: ...

PS:
[format "Es%i" $j ]
Can i use other chars instead of % which its have the same function ?

Hi,vesna, Thank you very much! And in this question,if I have a file :!: *.txt or*.out :!: ,which consider Es value: 10000 12000 14000 .........40000 50000 ,how can i do call *.txt or *.out in opensees? That is ,if i can call this file ,i can not input the numerical value of Es in opensees . PLS tel...

Hi, There is a big question in my code, i need calculate my code 100 times because it has a variable which has 100 value. For example, set Es 10000; Es is a variable and Es ={10000 12000 14000 .........40000,50000} it is 100 value. I want :?: write a loop :?: in opensees to calculate my code (source...

Hello, all The constraints is used by Plain in my plain. Then,when i analysis the gravity static analysis, I got the message following like: WARNING PlainHandler::handle() - constraint at dof 0 already specified for constrained node in MP_Constraint at node 3 WARNING PlainHandler::handle() - constra...

And I find another question, for example,i assigned "uniaxialMaterial Elastic 2 $E " set E 1000. Now if the E is a variable,and E is a assay,for example,E={10000,100002,10005,10010,10058} IF i want to get different engin result to different E what can i write the code? Can you tell me the ...

Thank you ,vesna,the problem has been resolved.thanks

Hi,vesna,i have tried it,but there are some warning .so i send a email to you in your email box,pls help me and let me know where is the problem?

Hi, I have a simple 3D truss with simply consider all node have zerolength element.all zerolength elements are connected by equalDOF command in horizontal and vertical directions and 45 degrees in x-y plane. The connectivity for the l degree of freedom is enforced by zeroLength elements with elastic...

Hi,vesna, Now i have a question. in my element,could you help me explain the below zerolength -dir and -orient meaning? element zeroLength 17 1 101 -mat 1 -dir 1 . element zeroLength 18 1 102 -mat 1 -dir 2 . element zeroLength 19 1 103 -mat 1 -dir 1 :?: -orient 1 0 1 -1 0 1 :?: if the global coord i...

Dear vesna,
could you give me some examples about the" zerolength command" ?
I find some examples in opensees Examples Primer,but i found that i can't understand the rlelationship about the zerolength and the equalDOF.
so if you have some examples ,please let me know .thanks!

Hello,vesna, i want to analysis a 3d truss ,i consider the node have zerolength elements,but when i run the below code,i found the results is not correct. i guess the equalDOF command is not correct assign.I changed the $dof which is in the equalDOFcommand many times,but i can't get the right result...

Hi,vesna,about the 3d truss model,if i have assigned all the zerolength element,should i use equalDOF command to assign the same coord node boundary? that is ,for example ,i assign node 1,101,102,103 have the same coord,and i use zerolength element connect 1-101,1-102,1-103,how should i assign the 1...
