Re: How to model a nonlinear shell element in OS

Hi, sure you can. "I must note that due to an error in the source of OS the code does not accept all arguments during object creation: int numData = 6; in line 65 should be int numData = 11; so the .exe must be re-compiled for this to work at all." This is an error I found in the source co...

Re: How to model a nonlinear shell element in OS

Hi,

You'll have to recompile OpenSees. Check my note in the opening topic about the error in the source code.

Cheers

Re: How to model a nonlinear shell element in OS

Hello Leopoldo, thank you for the fast answer! You are right, node numbering was incorrect and this caused the problem. With the third node number corrected, my example yields results quite close to those of ansys (9.21 vs 9.43 mm, 4.29 vs 4.55 mm). The difference is likely due to discretization, i....

Re: force based element, element mass density (per unit leng

Thank you, Vesna. I did not point it out, but my aim is/was to use this approach to model the dead load of the structure to use it in a static analysis. If I understand correctly, your answer means the masses defined using the <-mass> option are not included in the load vector. Anyway, since then I ...

Hi liwei,

how did you make it work? Could you provide a code snippet? I did not succeed even with the source code :-/

force based element, element mass density (per unit length)

Hi, I've been considering to apply the mass of my structure using the <-mass $massDens> option of the Force-Based Beam-Column Element in OpenSees 2.3.2. My idea is to use this option together with an applied constant acceleration (gravity) and thus calculating and defining the mass for each node of ...
