new material

[gst77]

Hi,
I followed the instructions in "Addingyourcode.pdf" to add a new material. I had the .dll file but I have the result: "WARNING could not create unixialMaterial masonryFC"
I'm running a machine with Windows 8, 64bits, and opensees 2.4.4 rev 5774.
I followed the next steps:
1-I have the masonryFC.cpp and masonryFC.h files of the new material.
2-I had the masonryFC.dll library using the files in the folder /developer/cpp and /developer/core

I have read in some posts that I have to modified the "classtag.h" file. I did it, but I don't know where put this file because it is not used in the tutorial.

Thank you very much for your time and help!

you don't need to edit the classtags file.

are you using 32 or 64 bit and is the revision of the svn code you checked out in agreement with the revision tag of the .exe?

Thank you Frank! I have my material running now!!!

Hello
i want to improve a material in opensees , first i have used your practice that name is ElasticPPcpp for, what do i need to learn? eventually i could make dll file and i have checked the output with your output and it is good output reasonably.second i have tried to change the name if uniaxialmaterial ECC01 to ECC02 for chek output with my output of ECC01 but i couldn't.
i will be grateful if you help me ,where is/are my mistake's?

best regards

[fmk]

if ECC01 works and ECC02 does not .. you either have not replaced ECC01 with ECC02 evrywhere or you have not created a DLL with the correct name

[shokri]

thank you for your answer and i have cheked 2 points that you sayed,and i have replaced ECC01 to ECC02 evrywhere and also i have created DLL file.
I run program and my *.tcl file's connect with dll file's but when i use one of output , for example strain stress recorder , my output when i check with ECC01 , i can't get same answer.
thank you for your attention

[fmk]

either the files are not the same, or the optimization settings are different and as a consequence the code generated may be different. are differences large or small.

Dear fmk
thank you,i could make Dll file,and it works right.another question is,how can i make Dll or exe file with fortran code,do you have useful files for it?

i will be grateful if you help me.
best

which functin can i introduce the parameters that use in all of function?

[shokri]

Dear fmk
why in command prompt window showes material failed in setTerialStrain() when i use new material that i added with Dll file?
where are mistakes?
and which function can show amount of special parameter in command prompt? for example i introduce parameter R, and i want amount of it in each level of analysis.

if it is failing there at least it is seeing your material. i suggest you debug the code of yours by putting in some output stamenets when it gets into your method to see what is going on.

if you have a variable R defined in your material, fill in the setResponse/getResponse methods and you can access it in your scripts or in a recorder.

Dear fmk
i want useful example of debug code and setResponse/getResponse method,can you give me some of them?
and is it a way that connet opensees with matlab code in adding new material? i have matlab code and it is work correctly.
thanx

[fmk]

you cannot add matlab elements or materials to OpenSees.

look at the UnixaialMaterial class for how to implement the setResponse and getResponse methods

[shokri]

Dear Fmk
how can i input parameters with initial data that in frist trying for SetTrailStrain function,Considered this input but after that do not this data?
i guess something but i want be confident.
best regards
