As for error:
libm.lib(libm_error.obj) : error LNK2019: unresolved external symbol _errno referenced in function ___libm_error_support

My solution is to add the file "VC2005errno.cpp" into the project failed.
The file "VC2005errno.cpp" locates in OpenSees/Win32.

Great solution!
Thanks a lot!

I have a deeper understanding of the library files "LIBIFCORE.lib" and "LIBIFCOREMT.lib". I guess they are the calculation module for OpenSees and are written in Fortran. In fact they should be generated by the same codes (IVF, Intel Visual Fortran) with different project setting...

Thanks Dr. Frank McKenna. I saw this solutions two days ago, and then I tried but failed. Today I tried this method once and succeed. This error libifcore.lib(for_init.obj) : error LNK2019: unresolved external symbol __pxcptinfoptrs referenced in function _GETEXCEPTIONPTRSQQ is caused by the library...

Basic description: OS: win7 SDK: vs 2012 ActiveTcl: 8.5.16.0 (32bit) tortoiseSVN (repository url) svn://opensees.berkeley.edu/usr/local/svn/OpenSees 1. empty the file Win32, then update to revision: rev 5855, update depth: working copy (make depth sticky: checked) 2. open the solution "OpenSees...

Thanks for your advice, fmk.
I have written email to the developer Jon Mohle last Friday.
I will write to Prof. Kunnath directly this time.

The explanation about the reinforcing steel material is shown as follows: http://opensees.berkeley.edu/wiki/index.php/Reinforcing_Steel_Material Where in Figure 3, the modified formula from Gomes and Appleton(1997) is given. Who can give the detailed explanation about the modification of the Gomes a...

In OpenSees, can force-based element(forces are the variables, the equations are based on flexibility matrix ) adopt explicit material model (to describe the stress-strain relationship, strain is variable, stress is the function of strain)? For example, define one material using steel02, then define...

I found this material could consider the nonlinear buckling, so I would like to try this material.

Not yet. Thanks for your reply. I will contact the programmer of this code. I will add the answer of my question after I get reply.

Is there somebody who knows how to apply the uniaxial material steel03 in the material library, in order to simulate the behavior of reinforced steel bar in presence of buckling? There is one uniaxial material steel03 in the OpenSees, however there is no introduction about how to use this material. ...

Hi, I built one new material.dll and attached the solution to OpenSees.exe to debug. However the breakpoint in my solution cannot be hit. I developed one new material for OpenSees and succeed in generating it as dll (for example named it as myMaterial.dll). Also the OpenSees can load myMaterial.dll ...

Hi, Alberto I developed one new material for OpenSees and succeed in generating it as dll (for example named it as myMaterial.dll). Also the OpenSees can load myMaterial.dll file by testing in test.tcl script. However, I found the material doesn't work properly. So I want to debug my dll solution (m...
