Hello, I think that there is an error in the main function of the quickmain project. In version 2.2.1 there is reported one change in code: 2. redo of how tags were cimplemented for MP and SP constraints I think that since that version, the SP constrains definition in the main function should be: //...

Hi, I have experienced some issues during downloading and compiling Opensees V2.3.2. 1. The link in the developers area os for the 2.3.0 version. At least this is the name of the zip file. 2. Then I have downloaded the 2.3.2 version frm SVN. It works OK. 3. Using Visual C++ express I tried to open t...

Hi Aizen, The element 1 (beam between 1 and 2) is able to rotate free in their axis if you only fix the translations DOF, so this is in my opinion the cause of the error. This is similar to modelizate a simply supported beam fixing the 1, 2 and 3 DOF. Usually this fails. This only happens in your mo...

Hello, I'm not familiar with Uniformexcitation loads and they do not appear in the post, but I think that there are some wrong things in your code: Your sample is uniaxial but you are using a 2D model I think the Y degree it is not fixed (the zerolength is only for X degree). You could try with equa...

Hello, if there is a non linear problem, I would suggest you to apply the load in several steps changing for example integrator LoadControl 0.1 analyze 10 The other possibility is that the system it is not stable. For me the other question is a little bit surprissing as it should stop the analysis a...

Hello, In my opinion the most required feature is to have a pre-processor and a post-processor. In order to integrate the OPS framework with geometric packages in an easier way, I think that some features are needed: Possibility of obtaining Rigid body shapes in eigen analysis. Now it is quite diffi...

Hi Frank, I can imagine from your answer that you are preparing a new version for the Parallel Workshop. 1. Is this new feature of adding external solvers related with Parallel computing or is an indepentent one.? 2. Will you include also additional solvers or we must develop them?. 3. I'm specially...

Hi, I would recommend you to have a look to OpenCascade: www.opencascade.org I think it is quite similar to VTK, it is free (even for commercial uses) and it also supports TCL. Of course there are also some "minor problems" as there is not any official support. There is another related cod...

Hello Silvia,

Are the presentations of this workshop available for downloading?

Hello, I have installed MPICH2 on my Core duo labtop running with Windows XP and I also have been checking the presentations of the workshops. I have some doubts about how to run a script with parallel computing. I'm able to run Opensees.exe an existing script on both processors using: mpiexec -np 2...

Hello Silvia,

I hope you have enjoyed your long holidays, in the european style.

Could you please tell me if the presentations of the last workshop will be available?

Hello, You can also download the file for the Unix version (http://opensees.berkeley.edu/OpenSees/code//OpenSees1.7.4.tar.gz). I did it and I descompresed it with Winrar. As it is stated on point Nº. 4 of the source code distribution chapter, it contains the same code that the Windows version. (The ...

Hello, I have read on the change log of the V1.7.4 version that has been added some code for building a parallel version. Unfortunately, I have checked the source code (the link of the windows version is not rigth. I have use the link for the unix version) and I have not found any instructions or so...

Hello, I have a new laptop. It has an Intel Core 2 CP T7200 @ 2. GHz processor with 1 Gb RAM. Opensees V1.7.3 runs only at 50% of the capacity of the computer. I heared and read something something about parallel version of OPS but I'm not sure if this applies to this case. Could you give me some ad...

Hello Frank, I not really interested on modify the code, only on using it. I have seen that exist the file corotational.lib and that the binary file Opensees.exe works with the Corotational transformation. I think that my real problem is that I'm not skilled on C++ and I do not know how to compile t...
