Hello, i want to give a temperature function to a boundary. How looks an usersubroutine for this problem.

Thank you very much for your help. Torsten

Have you taken a look on the sample coding provided in Star ?

I have, but i havn`t found anything. Perhaps i have found a method of resolution.

IF(IREG.EQ.0) THEN U=0 V=0 W=0 TORHF=293+345*log(8*TIME+1) !that´s my temp.function SCALAR(1)=?? RESWT=0.05 RSTSC(1)=?? ENDIF

What stay for the question mark? Is the other code okay? thank´s a lot

Just create a little testcase and have a look if the coding works as expected.

I have never used a subroutine before. Do i have to select in Run Analysis Interactively YES for the question "Do you have User Subroutines?"? What have i to do with the boundary conditions? What have i to select for Wall Heat? Thank´s

YES, you have to select yes. if you don't run star interactively and use starlink, you are asked, if the compilation should be checked or something like that- then you can see the errors. The boundary condition should be USER. Normally the subroutine bcdefw.f is used then, and there you can add your user coding
