The code above works well using the latest TAG as it was fixed by Frank McKenna (Many Thanks!)

Thank you for reply Frank! That would be really great! I don't really have options now for UP elements left and really need to simulate construction stages with UP formulation. P.S. One thing I noticed is if I run the same problems but with all side nodes fixed in x-dir, I don't have any issues. But...

Hi there, I am trying to simulate a stage construction using 9_4_node_quadUP element following Frank's advice in previous post (http://opensees.berkeley.edu/community/viewtopic.php?f=2&t=62065). Now when I am adding new nodes and element, I get tensile stresses before even self-weight of that el...

Thank you Frank for clarification!

Thank you Frank! Exact same situation for Nine_Four_Node_QuadUP element, I would guess that being 2D element it requires: eleLoad -ele 1 -type -selfWeight 1.0 1.0 but this again only works on Windows! On MacOS it can be run only with: eleLoad -ele 1 -type -selfWeight 1.0 1.0 1.0 which seems not what...

Hi there, I am experiencing problems while using eleLoad command. OpenSees returns segmentation fault: 11 on MacOS, but exactly the same input works just fine on Windows. Other inputs where I do not have eleLoad command work fine on MacOS. Any clue what could be wrong? The input is below followed by...

works just right! Thank you alborzgh!

I still have not resolved the problem, but a colleague suggested to use eleLoad load pattern. So here is what I do now: - add elements using: element quadUP $elTag $n1 $n2 $n3 $n4 $thick $matTag $bulk $fmass $hPerm $vPerm $gx=0 $gy=0 $t=0 - add load pattern using: pattern Plain 1 {Series -time {0 50...

Thanks for your reply,

I assign gravity to quadUP elements, density to material and then run analysis

Hi, Is there any way to apply self-weight in linear load pattern manner? I'm using quadUP element at the moment, but this is an issue for other elements (e.g., 9_4nodequadUP, brick, brickUP). When I assign self-weight to an element and run analysis, self-weight is applied instantly. Is there any way...

So I guess there is a command that could read current load at a node, something similar to displacement read...

Hi Rain, Have you eventually figured out the solution? I need to do the same for my simulation and have discussed with a friend about the issue. When you fix pore pressure (PP) DOF, you force PP=0. Therefore, if after undrained loading you fixed PP DOF, then it should force PP=0 suddenly. In your ex...

Hi, Is there any way, in transient analysis, to apply displacement pattern but have a load limit for it? I'm using SSPbrickUP element to simulate undrained triaxial compression with own material. I'm applying displacement pattern: set VdispInitial [nodeDisp 5 3] set Vdisp -0.01 set Disp [expr $Vdisp...

I have similar problem! What I did is checked out a previous tag 5363 (used to generate v 2.4.1); however, I get different kind of error LNK2019/2001: "extern double dbesi0/dbesi1 in KikuchiBearing.cpp/MultipleNormalSpring.cpp/MultipleShearSpring.cpp is unresovled symbol". This is linking ...
