the write command ? i cant find it - how it works ? it crashes when interprets the write command :s is htere write command in tcl ? what about puts ? in more detail i have created two files one is pload.out ( they contain one column ( with 50 elements each) and the ather is uload.out- what i am tryi...

thank you very much but the problem remains to make the substraction between the elements of two subsequent lines

there is something not so relevant with the topic i opend buti would appreciate if you could help me with opening reading and writting values into a file. i have a file with two columns ( lets say p and u) after an analysis i want to open the file read the values from the first line to the end and i...

is it able for the nodes of a model to be shown using vees? because i have my full model and deformations but not the no's of elements and nodes

is it my error or is not supported by vees

thanks

! oh yes!
i 'll try with vees

silvia i would like to ask about stress strain recorder- it depends only on the kind of material law that has been used ? for instance if we use a steel01 material the results in stress strain recorder will be pure tension or compression stress ?? morever what about K stiffness recorder on section l...

yes i pasted exactly in the way you describe to call it

hello and happy new year
i placed the proc after the modelbuild and nothing happend just like there was not there

i am reffering to the Example 2. 2D cantilever column, dynamic eq ground motion

may you help me
thanks a lot

Hello i would be glad to know that someone of you has tested and find a routine that calculates the effective period of a yielding structure, for example under a NSP ( nonlinear static proc.described by FEMA).

is there any preparation for the opensees to take advantage of the dual core power ? in this time opensees is running only in one CPU unit ( dual power processing would make the things muuuuuch better)

thanks

well i have tried to use section Bidirectional $matTag $Es $Fy $Hiso $Hkin element zeroLengthSection 100 1 2 10 and i have earthquakes at two directions . unfortunately the results using recorder Element -file force100el.out -time -ele 100 force recorder Element -file deformation100.out -time -ele 1...

ok silvia i send a zip file containing two versions of the file . The second one is the case using the mass command , but i failed again.

i am waiting for your valuable answer.

Thanks in advance

yes i have already done this silvia , but i think there is problem with nonlinear beam column element and mass density option !

please if you have an example with element definition ( mass density embedded) please send me or write down where can i find it .

NG

yes i know this option and i have visualizes the eigenmodes . i think that the eleload command has a problem , do you have any examples where a lumped mass matrix is formed by this way ?( eleload)

i still take the first mode rotational
