Thank you vesna!
Is there any script available so as to give me any idea of the procedure you are talking about?
Once again, thank you!

mass participation in modal analysis
Dear all,
does anybody know if I can get an output file with the mass that is activated in each mode in a modal analysis?
Thanks in advance!

corrotational truss
Can anybody explain to me what exactly the "corrotational truss" is?
What are the degrees of freedom that this element has?
Thanks!

rotational springs
Does anybody know how I can model rotational springs to the base of a structure?
Thanks a lot!

Re: pattern plain
Vesna, thank you for your quick response. Now, I'm dealing with another problem. I want to perform a dynamic, time history analysis by considering the gravity load. The gravity load is imposed as nodal load with the pattern Plain Linear. Firstly, I run the gravity analysis. Then, I write on the scri...

pattern plain
Dear all, I have modeled a soil-structure-interaction system and the soil is modeled with quad elements. The applied load is a time series with the following command: pattern Plain $patternTag $tsTag { load $nodetag } where the $nodetag is a node at the bottom of the soil profile. The command "...

Hi everybody! In the command manual of Opensees-http://opensees.berkeley.edu/wiki/index.php/Drucker_Prager- the example of a brick element with the nDMaterial Drucker Prager gives the following note: "the element is loaded until failure, at which point the model can no longer converge, as this ...

Problem in recognizing the brick8N
Hi! I'd be grateful if anybody knows how the brick8N can be read by the opensees. When I write the following script: wipe; model BasicBuilder -ndm 3 -ndf 3; # nodal coordinates: node 1 1 1 4 node 2 -1 1 4 node 3 -1 -1 4 node 4 1 -1 4 node 5 1 1 2 node 6 -1 1 2 node 7 -1 -1 2 node 8 1 -1 2 node 9 1 1...

Hi! I have simulated a structure with brick8N elements by using a model BasicBuilder -ndm 3 -ndf 3. But, when I try to run the script, it posts a warning message: "WARNING NDM=3 and NDF=3 is incompatible with available frame elements". Just to notice that the only type of elements I have u...

Brick elements-mass and loads
I have a structure consisted of brick8N elements and I'm dealing with some problems... 1)Since I have defined the mass density (mass/volume) during the definition of the brick8N element, is it sufficient for the dynamic analysis? 2)Can I apply the gravity loads to these brick8N elements using the co...

How can I simulate the nonlinear behavior of an unreinforced masonry structure in a model of shell elements? Is it adequate if I use the nDMaterial Drucker-Prager or should I use another material in order to take into account the constitutional law? Is the "template Elasto-Plastic" materia...
