Hello. When the following cyclic loading is performed, the output reaction is not incrementally analyzed with the horizontal force sp command while maintaining the value after 10 steps of the vertical load. The sp command ran correctly in Python code, but not in Tcl code. I'm using opensees 3.2.0. a...

I can read "designspectra(0). And the calculation was done. However, I get an error and stop at the following points. ********************************************* Calculating ductility... Level 1 Deformation: 1.34585 Level 2 Deformation: 1.06504 Level 3 Deformation: 0.672844 Level 4 Deformatio...

I have something to ask and I will post. The following useful code causes an error in "Eqscaling.tcl" when reading a seismic wave. can't read "designspectra(0)": no such element in array The seismic wave was used as the response spectrum, and the acceleration was stored in the fi...

I posted a question about how to set Pin springs in 3D frame analysis. As shown below, the X direction is the beams, the Z direction is the girders, and the height is the Y direction. When I set the section Aggregator as follows, the linear analysis will reflect the bending stress results of the pin...

Dear rafal and skypass


I use matplotlib ver. 3.2.1.

I updated to ver3.3.4 and it was successful.

Thank you for your advice.

Hello. When I run the following example file, I get the following error: https://openseespydoc.readthedocs.io/en/latest/src/ops_vis_ex_3d_3el_cantilever.html#ops-vis-ex2 Traceback (most recent call last): File "demo_cantilever_3el_3d.py", line 69, in <module> opsv.plot_model() File "D...

Hello! In the Pinching4 setting, setting ePf4 and eNf4 to plus will succeed. (ePd4,ePf4) , (eNd4,eNf4) Setting ePf4 and eNf4 to negative gradient will result in an error because we want to consider the negative gradient. set pEnvelopeStress [list 31.19e3 55.00e3 80.00e3 32.00e3] set nEnvelopeStress ...

Dear Alvaro

Finally succeeded.

Thank you for the advice.

When I ran it as follows, the error disappeared and the compilation was finished. 1)Added sectionforcedeformation.h and bool.h to the \core folder and source folder 2)Added CrdTransf.cpp and sectionforcedeformation.cpp to the \core folder and source folder 3)project properties>preprocessor definitio...

I posted something I would like to ask. In the SAWSMaterial.cpp file, it says that it was migrated from FORTRAN to C++. I'm new to C++, so I'd like to study the original FORTRAN code. Is the FORTRAN code published somewhere? I've heard that OpenSees are related to DRAIN-DX(2D・3D). I bought it in 200...
