transient temperature distributionT(x,y,t)

May 12, 2004, 08:16

hello .I have a simple 2D conduction heat in a solid(a rectangular plane surface ).(no vonvection and radiation) and I have take a stationary heat flux throught an edge as BC. I can display the stationary teperature distribution T(x,y) but I want to obtain the temperature distribution at any time T(x,y,t).DOES any body tell me what to do please???thanks

FLUENT doesn't keep in memory the value of each variable at each past time step.

If you want T(x,y,t) you have to save a dat file, for example after a costant number of steps and then postprocess them in order to obtain the data you need.

hello. can you tell me how to use UDF to save the data file and post process it? and what time step you mean?? can yopu be more clear please??....THANKS.....

you dont need a udf for taht just use file --> autosave

also, i think animation feature will be really useful for what you are trying to do.

I agree with co2, you can activate the Autosave option in the File -> Write -> Autosave menu.
