Hi
Does noone knowe how can i to activate temperature in abaqus procedure?
i know this ways?
property->temp dependor
step->other->temperaturebut
in this ways we only add one(1) temperature but i want to changing this temperature step by step in all of the ranningjust same as changing of stress?
it is right that changing of stress is result of changing load but
 i want to know is any way that to activate changing of temperature in all of the running without of activating the thermal load or thermal step.i want to do this in a general mechanical step.regardbinam

*TEMPERATURE .... , USER

in conjunction with User Subroutine UTEMP. This will allow you to set temperatures at any or all nodes in the model as a function of node position and analysis time.

Is that want you require?

RE: [b]PLEASE HELP ME IF CAN?[b]

You can assign temperature as a predefined field in a static general step and change it during a step using amplitude.

Hi
Dear amubashar & mrgoldthorpe
thank for your reply and your favor
in the utemp there isnot term of DDSDDE and i think that only in umat is.because i work with umat for changing property of material and my project is composite.
and i had used from predefined field in a static general step but it cannot solve my problem because i want to chang temperature in any moment continuously automatically.
In fact my  questin:
I want to write a code of umat that in it I need to use TEMP and DTEMP.
now i want to know how can i activate these terms (TEMP & DTEMP)in cae file or in umat code .
i think they are inactive because when i wrote a umat code  and added this instructino:(write(6,*),temp ,dtemp) then  run with its abaqus cae file ,at the end ,when i checked the valu of them in temp file of C drive
i saw the valu of both of them were zero (0) but(while) i need and  expect that they get valu .
now what is the suggest of you for solve this problem?Regard
