Did you try the latest version of 2.4.0? I compiled it 2 days ago, and it is working very well.

If I remember correctly when I did this check with my friends, "elasticBeamColumn" element does not support mass density well.

Hi, Frank Thank you. Yeah, that is what I thought, but I have a case which is not working as we thought. I am sending you the example I have by email. In order to repeat the problem I have, you just need to run the example and wait for less than one minute (with successful "analyze" for th...

Hi All I have a question on OpenSees as shown in the title "what is changed for the domain if I do "analyze 1" but if it failed with the following error message: analyze failed, returned: -3 error flag I think the domain is not changed, but I the following problem I had below confused...

For now, it works fine according to the check I did.
So we can save lots of trouble to define gravity load directly. Instead, we just need to define mass, and then define constant acceleration g.

Hey vesna Thanks for your reply, but I did not get whether you agree or not. Yes, in OpenSees we need to define gravity loads. But the gravity loads can also be obtained by applying constant acceleration of g, without defining gravity load directly, right? vesna wrote: > In OpenSees there is such an...

Hi, Guys When we apply gravity loads for a structure in OpenSees, did you try to apply a constant acceleration "g" instead of applying the loads by any chance, which may save us lots of trouble. But I did not see much of this in OpenSees, which can work in other software like ANSYS How did...
