Dear Friend You need to include the bin and library functions before you install opensees. Are u using windows or unix. In case of windows, you require a c++ compiler and tck and tk installed on ur system before opensees can run. In case of unix, check out the message board, there is a detailed proc...

What is the procedure getting P-M interaction for steel columns using W steel sections. Can anyone please suggest the procedure of getting the P_M curve and using the same in nonlinear Beam Column Element? Also while defining the nonlinear beam column element for steel girders, I gave the following ...

I am carrying out the modelling of a steel frame using I sections. I want to model the columns so that they exhibit the P-M interaction. Opensees doesnot specify P-M interaction diagrams for different materials. How can I get P-M interaction for steel I sections. Also, I am working with nonlinear Be...

For a multistorey frame, how do we find out the natural frequencies and mode shapes. I tried the eigen command, but it is giving the eigen vector corresponding to each node rather than for the whole structure. Also, it is not giving the frequencies along with the eigen vectors. I used: eigen 1; prin...

Dear Sukumar, Thanks for ur concern. I have not achieved success with installation of opensess till now. Actually I shifted my attention to some other stuff of my project from some time.. But i will be really thankful if you could send ur makefile.def. I am using Fedora Core 5. My mail id is vishalb...

Dear Sukumar,

I have replaced the makefile.def, but I am not able to debug the error message that i mentioned in the previous post. Can u suggest something regarding the error, because the make installation doesnot get completed due to that error.

Dear Sukumar, Well i went through ur mail posted to pallavi and got the procedure for installing opensees through X11.

Dear Sukumar and all, As mentioned by u, I looked at ur post to pallavi where u have suggested the way of installing opensees through open gl. There are some problems: while installing gcc, gcc-g++, etc, the yum command gives the following error, "Cannot find a valid baseurl for repo:core"...

I got the makes directory and the makefile.def of my interest. Now do i have to make the changes inside this file. If yes, then the $ HOME variable is specified at more than one location in this file. Where and how many changes have to be made and what are the changes??
