Thanks!

I did v1.7.3 well but fail when v1.7.4. So, I don't think that the tcl installed in the wrong location. The reason may be in the codes.

Compile Opensees v1.7.4,error?

I download the code of version 1.7.4.

My system is windows. The error occurs with "tcl.lib". Does anyone successfully compile this version. Give me some suggestions?

Thanks! :D

Your Tcl version may be a little high!

I also encountered the problem. Then,I used a low version Tcl and the compile is success.

May be helpful to you!

It’s a good question to discuss,in my analysis(take account P-Dalta),if the convergence problem ids global,i.e.the displacement is always increase in one direction.Either I use smaller dt or other arithmetic,is failed to convergence also,does anyone kown some methed to improve the problem(I mean mak...
