OpenSess V2.4.1

[etm]

Hi
I've just downloaded OpenSees 2.4.1, but I faced a serious problem!
the last version which I work with was 2.3.2.2 and I had been verified and EBF's Link performance using uniaxialMaterial Bilin befor I downloaded version 2.4.0. the interesting part is that the same thing that I wrote now runs completely wrong and new answers are far wrong. I tried this for version 2.4.1 but it gives the same wrong answers, I run it through V2.3.2.2 again and the answers were right again.
could anybody tell me what's wrong with newer versions of OpenSees?!!
I should say that the ActiveTcl 8.5.14 is installed on my computer.

Thanks for helping

it's probably due to one of the many changes to the material, version 2.3.2 was release tag 4665. as you see from the following there have 6 major changes, bug fixes to the code.

i need a simple single material, single element script that outpus the stress-strain relationship showing it is wrong so that i can contact the many contributors to the source code to see which one of them messed up.

that's so kind of you dear fmk
here is the script needed!

uniaxialMaterial Bilin 88 $K $alpha $alpha $My [expr -1.00*$My] 0.5 3.000 5.000 0.9 0.4 0.8 1.00 0.6 $dp $dp $dpc $dpc 0.25 0.25 5.00 5.00 0.1 0.1

element zeroLength 34 1 11 -mat 88 -dir 6

I hope that's enough

what exact version of 2.4.1 are you using (i.e. is there any numbers after the 2.4.1). Dimitrios has updated the software since the official release and we have put out to minor releases since (2.4.1.1 and 2.4.1.2). if you are using 2.4.1.2 and still have problems, i will probably need a stress-strain response from you that demonstrates the error.
