Adding new material

[JOSELUISEM]

Hi, everyone,
I been successfully following the "Implementing Your Own Material in OpenSees" tutorial. Now as second step, I've decided just to try modifying only the name of a copy of the steel01 material but I'm missing something, this is what I done:

1.- a change of all variables and files in (Steel01.h, Steel01 .cpp) to (trialMat01.h trialMat01.cpp)
2.- an addition of "#define MAT_TAG_trialMat01 76" in classTags.h
3.- I get the trialMat01.dll file like in the tutorial without warnings
4.- Also I've checked "virtual int setTrialStrain (double strain, double strainRate =0) =0;" in uniaxialmaterial.h

I'm using OpenSees 2.4.4 rev 5755, VS 2010 and win7. Also I've tried it in OpenSees 2.4.4 rev 5755, win8 and VS 2013 with the same results:
"WARNING could not create unixialMaterial trialMat01"

Which is the right way to do this? Thank you for your valuable time,

[JOSELUISEM]

NOW IT'S DONE TY.

I'm having exactly the same problem.

I also get the trialMat01.dll file like in the tutorial without warnings.
but I get this message also: "WARNING could not create unixialMaterial trialMat01"

How did you solve this problem?
does anyone know how?

I'm so desperate to see the answer.

[fmk]

are you using the 32 bit version of the .exe

Hi fmk
i made new material with dll , but when i use this code,the matrial dosen't fail but i can't plot stress-strain because the stress equals zero.
i used your tutorials.
where is my problem? where is in my code i have mistake?
i will be grateful if you help me.

[fmk]

in your code put some debugging statements, e.g. before the return from setTrialStress() or getStress() put a debug satement such as:
opserr << "trailStress: " << tStress << endln;

[shokri]

Dear fmk
thank you for your attention
i used this debugging statements but my problem didn't solve and in command prompt shows Tstress:0 in each strain.

[fmk]

well in the setTrialStrain method put something similar that outputs the strain and the stress at end of routine. if strain not 0 and stress 0 the problem lies obviosuly in the method. if it is always 0 it means either your script is garbage.

[shokri]

Dear fmk
explain obviously this line in previous command:
"in the setTrialStrain method put something similar that outputs the strain and the stress at end of routine",which codes shall i put? i khnow just one code that you said for getStress().and when i put this code in getStress(),and in getStrain() the strain was not 0 but stress was 0.
and when i put this one again in setTrailStrain no strain and stress i can't capture,what's wrong in setTrailStrain?
