Dear all,
Is there an axisymmetric quad element with and without pore pressure DOFs ?
If there is no axisymmetric elements in OpenSees, is there any reference could guide for developing such elements in Opensees?
Best Regards

Shell element
Dear all
In the manual is mentioned for shell element the nodes must be in counter clockwise order. But in the example for that element in http://opensees.berkeley.edu/wiki/index ... ll_Element , nodes are in the clockwise order. Would you mind helping me which one is correct?

Flow Liquefaction with PDMY material
Dear all
Has anybody ever modeled flow liquefaction with PDMY material?
The mechanism of liquefaction in PressureDependMultiYield material is cyclic mobility (non-flow liquefaction) but in the manual there are 5 optional parameters in the PDMY material command based on the work of Li and Wang to define critical state line for modeling flow liquefaction. I am modeling loose sand and I want to model flow liquefaction but when I use those 5 optional parameters there is no difference in my answers between this situation and the state I don't use those 5 parameters and for example displacements increased incrementally cycle by cycle similar to cyclic mobility. Would you mind tell me why there is no difference in the results when I use or I don't use critical state parameters and why the flow liquefaction is not modeled?
Thanks

Re: bbarBrick element
The body forces input into the some kind of elements should be the components of the gravitational vector ( gravity acceleration components in x, y, and z directions , for example 0 , 0 , -9.81) like BrickUP element , and in some elements the body forces should be the unit weight.
I meant which category of elements include bbarBrick element ?

Re: bbarBrick element
Thank you for your attention
Are they ($b1 $b2 $b3) gravity acceleration components?

bbarBrick element
Dear all
How can I apply body forces in bbarBrick elements? In the command of that element there is no parameter for body forces!
element bbarBrick $eleTag $node1 $node2 $node3 $node4 $node5 $node6 $node7 $node8 $matTag
Thank you

ZeroLengthContact element
Dear all
I want to use zeroLengthContact element. Could anyone guide me how I can evaluate penalty parameters in the command of that element?(penalty in normal and in tangential directions)
Thanks

Dear all
Is anyone use ZeroLengthContact Element for modeling soil-pile interaction?? How can evaluate penalty in normal and in tangential direction for the command of that element??
