Just support out of plane displacements...

You should look up the manual at my web site:

There was a number of examples during last workshop aout doing staged construction, we do it regularly, first build up the model and then excavate ...

See if you can find slides from the last workshop, I had some examples and links on some of my slides...

the template material models are for 3D, you can use 3D brick to model 2D plane stress or plane strain model by appropriately fixing and releasing boundary conditions, the only overhead is then in doing constititive integration twice for integration points that have same X-Y corrdinates (assuming th...

We have all these input files, and they have been posted to that web site for last two and half months:

http://sokocalo.engr.ucdavis.edu/~jeremic/PDD/

look at the bottom of the above web site, there is link to two examples. More examples should be comming in near future.

one can use u-p or u-p-U formulatioon, both for fully saturated soils, there are some tricks one can play for partially saturated currently to get some sensible results... Both u-p and u-p-U can deal with saturated soils due to capilary rise (as long as there is full saturation...) In addition to th...

Hello Liam,

Try different solver and see what you get?

Boris

Yes we compiled 64 bit version on DataStar (SDSC)...

Have not tried on linux yet...

Boris

There is also a parallel version developed at UCD, and is available for public use now. We are runing it on a number of machines (SDSC datastar, UT TACC, our own cluster...). Currently we are checking installation on couple other machines, that is to be done by other folks (users), and will then dev...

There is rocking element developed at UCD by Gajan, will ask him when will he be willing to share it with the world...

Boris

Do you mean rocking of foundations?

Boris

do you mean MPI as in Message Passing Interface?

BOris

Can you package it and send it again!

Thanks, Boris

You are missing some support in your fixity commands, that is your model is allowed to move in x and z directions, it has rigid body modes and hence your resulting equation of motions might be marginally positive definite, it will not be positive definite if it was only used in statics, but mass and...

Take a look at the example from a workshop last month: http://sokocalo.engr.ucdavis.edu/~jeremic/OpenSees/OpenSeesWorkshopExamples/SingleElement/ and in particular look at: SolidTemplate.tcl This one example is using elastic-plastic material (through template EP concept) and is also using diffrent b...
