Dear, I am working on a simple model as Prof. Scott suggests, to know how to apply pore pressure. I created three layers, the middle one being a SSPBrickUP element and the other two SSPBrick, I want to initialize the model with gravity applying pore pressure of 10kPa on the porous nodes. For which m...

Dear, I tried to reproduce the example presented in the Brick u-p element. Below I am presenting the code. import opensees as ops ops.wipe() ops.model('basic','-ndm',3,'-ndf',4) a = 1 ops.node(1,0,0,0) ops.node(2,0,0,a) ops.node(3,0,a,0) ops.node(4,0,a,a) ops.node(5,a,0,0) ops.node(6,a,0,a) ops.node...

Dear all,

Can any one help me how can I assign density to sspbrick element with nd material Elastic isotropic.

Thank you in advance.

Dear all, I want to simulate Undrained Cylic Triaxial test using single element SSPBrickUP. I am attaching my code below as also the error when I applied Cyclic load. import opensees as ops ops.wipe() ops.model('basic','-ndm',3,'-ndf',4) ops.node(1,1,0,0) ops.node(2,1,1,0) ops.node(3,0,1,0) ops.node...

Hello all,

I would like to ask. How to apply acceleration due to gravity in openseespy. I am using SSP Brick Up element. Is it enough if I gave (0,0,-9.81) in the place of body forces for the element.

Thank you in advance for the reply.

Hello all, I am working on a model, with 30420 nodes and elements 27550. I imported the nodes through python and created nodes and elements. The model is working fine up to a certain number of elements (21761). If I increase the number of elements I am getting a kernel error. I including my script h...
