As an update, this issue is still unresolved, and DOES appear to be an issue with hybrid analysis. I attempted both -file recorders and -xml recorders, and both have a similar issue. Several recorders have the full data set, but many of them have an incomplete first line of data, and that data is no...

Hello, I had a few questions about using recorders with OpenSeesMP. I heard somewhere that -file recorders do not work well in OpenSeesMP, and that -xml recorders should be used instead. Most of my post-processing codes were designed for -file recorders, so it is a bit tough to look at the data. How...

Thanks Frank. I was able to use TortoiseSVN to grab revision 5621, but I am still getting errors (albeit different ones) when compiling in Visual Studio. I've tried VS 2008 and 2013. Also, I deleted my entire download and checked out rev 5621 from scratch, but got the same errors when compiling. I a...

I’m trying to compile the newest version of OpenSees in Microsoft Visual Studio 2008. I downloaded the code through TortoiseSVN (which I am very new to) and doing an ‘SVN Checkout’ from the URL “svn://opensees.berkeley.edu/usr/local/svn/OpenSees/trunk OpenSees”. I noticed that if I try a ‘Fully Recu...

I switched over to version 2.4.3, and I was able to run my analysis using UmfPack without getting the LValue error, so it must have been an issue with the older version. Unfortunately switching to the parallel SP version of OS at this time in our project is a bit too much effort given the custom cod...

I had some quick questions regarding the exact cause of the error message "failed to get compatible element forces and deformations", when using forceBeamColumn elements throughout a building model. I understand that this essentially signifies a loss of convergence, but in the model I am u...

Thanks for the response, Frank. I have confirmed that switching to a different solver (in my case I used BandSPD), I was able to run the model without any issues, and it showed agreement with my previous results in metric units. It is only when I use UmfPack that I get the error regarding Lvalue, an...

I version I have used with this specific example is version 2.2.2. The command I am using in OS to control the Lvalue is "system UmfPack -lvalueFact ###" The error OS puts to screen says the Lvalue must be larger than 5786294. That seems impossibly high to me. Also, what do you mean by &qu...

I have a very large model of an RC building that i have been working on converting from SI units to English units (it was not coded very efficiently, so a lot of this is done manually). As I am editing it, I am making it more flexible and consistent with recent examples such that units can easily be...

Hi, When using NormDispIncr, is the comparison normalized in any way to the initial target solution vector, or is that only done with RelativeNormDispIncr? Basically, is the NormDispIncr tolerance 'unit dependent' and 'step-size dependent'? For instance, if I reduce the size of a displacement step, ...

Hi Frank,

Were you able to take a look at this example and determine the issue with the database commands? We are rather stuck without having this working.

Frank, below is a 2-node cantilever system using the same properties as my full model. It produces the same error as the full model. # Inelastic RC Frame Example # Units: kN and m # # NOTE: to RUN this example, run Opensees and # type the command: source Frame_2nodeexample.tcl # Define the model bui...

Hi Frank, I decided to attempt a static explicit integration method using "algorithm Linear" and small load steps to apply these sp constraints. When steps are taken which are too large, the model obviously blows out eventually when using the nonlinear building model. I would like to imple...

Thanks for the reply Frank. I'm trying everything in my arsenal to achieve convergence on this building model. One thing that is giving me trouble is not being able to apply a set of sp constraints in small increments (for instance, apply the pattern of sp constraints 1/10 at a time, in 10 steps). I...

Hello, I am working with a large nonlinear RC building model (about 1500 nodes). OpenSees is performing a stiffness evaluation of a portion of the structure my moving each degree of freedom individually by small amounts. To do this, at each time step I am defining a Plain pattern which contains a la...
