Question about geotechnical examples

[jihun]

I download the files attached in the example Dynamic 2D Effective Stress Analysis of Slope (http://opensees.berkeley.edu/wiki/index ... s_of_Slope) , but I cannot run or modify the GiD file in GiD as introduced in the example GiD ProblemTypes for 2D Slope Analysis Input File Generation (http://opensees.berkeley.edu/wiki/index ... Generation).

I've tried GiD11.1.4d, GiD 11.0.4, GiD10.0.9, but none of them works and all of them return the same error information: This type of problem doesn't exist. I'm pretty sure that I saved the files in the same directory as advised in the example (C:\Program Files\GiD\GiD (version number)\problemtypes ).

Detailed information about the error:
1. After opening projects, the command window shows:
Layer to use: Layer0
17 conditions read
5 material read
2. Then Mesh->Problem tpye->UWnineQuad2Dup and the command window displays the information below.
This type of problem doesn't exist. Enter new problem type name:
unknown command-> C:/Program Files /GiD/GiD 11.0.4/problemtypes/UWnineQuad2Dup.gid
Leaving problem type function. No problem type

OS version: MS Windows 7 64bit

Hello,

I am facing the same problem. Did you get a solution? Kindly help.

Thank You

The files provided are not the mesh, but just the files to generate a tcl file.

You need to generate your own mesh first.
Then assign the properties as given in the problemtype and then export.

Hello All,

I am trying to create my model with mesh generation, but when I wanted to create tcl file, I faced with this error "Error in base file C:/Program Files/GiD/GiD 10.0.9/problemtypes/UWquad2D.gid/UWquad2D.bas at line number 209: Unknown command: 'xCoord'", I will appreciate if someone helps me to solve my problem.

Thanks,

Hi,

The free version og GiD has node and element restriction, although in many case this may not be a serious restriction. I find writing a Scilab (or MATLAB) function or script to write the OpenSees model is more convenient, provided you use a structured mesh. If interested, I will post one such scilab function I have used in the past for generating Retaining Wall-backfill mesh.

Regards.

The GiD code that you have downloaded from OpenSees website requires you to define Lysmer dashpots. The error message, you are receiving, is for the line that it cannot find the coordinates of your dashpot. You can either go to the problemtype file and modify the code in Lysmer section or define the dashpot in GiD and then remove it in your code.

Bests,
Soheil

oh great, i think i had to get the full version of GiD, thanks for the reply @ sb1966 and skamalzare , it's very helpful, first time being here, i really love this forum

May try gmsh (http://gmsh.info/#Download). Its a free mesher which is lightweight. One can do structured meshing by using "Transfinite" and "Recombine" commands, save the mesh in ASCII format and read it using MATLAB and then convert it to OpenSees. Good tutorials are available in youtube, (viz: https://www.youtube.com/watch?v=O4Ycezrv3V0) to start with.
