how to output stresses and strains in a element

Hi everyone, I am running the model: "Plastic Pressure Dependent Wet Inclined Dynamic" located at http://cyclic.ucsd.edu/opensees/Plastic%20Pressure%20Dependent%20Wet%20Inclined%20Dynamic/index.htm on opensees (1.7.3). Somehow, only node-related ouput, such as disp.out and acce.out, are ge...

Hi Boris, Thanks for your help. Based on the actual definition (eqs. 8.61 and 8.63) of RHS on page 189 of your lecture note, these virtual "loads" are the summation of tractions, body forces and pore pressure at BC. Based on my understanding, if I want to specify the pore pressure at some ...

how to set up boundary conditions in tcl for Brick8N_u_p_U?

Hi everyone, I am using Brick8N_u_p_U element to analyze a underground mined panel within saturated porous medium. Here are my questions: (1). For zero pore pressure boundary condition, for example at a node 6747, I can do this: fix 6747 0 0 0 1 1 1 1 The first "1" above means zero pore pr...

anybody has example tcl code for parallel computation?

Hi everyone, I am trying to use three PCs with linux system to do parallel computation with Opensees for my 3d FEM model. I am new in the area of parallel computation. I read the report at http://sokocalo.engr.ucdavis.edu/~jeremic/PDD/DraftReport.pdf and got some ideas: 1. explicit domain decomposit...

fmk,

I have installed vc.net. I can compile opensees1.6.0 successfully but still get a lot of error messages for opensees1.6.2. Are you going to update the project for win32?

thanks.

Hi everyone, I got the following error information when I compiled the OpenSees 1.6.2. Looks like the error is related to these two lines in SuperLU.h: superlu_options_t options; SuperLUStat_t stat; I can not find where the superlu_options_t and SuperLUState_t come from. Anybody knows what is wrong ...
