Default wall subtoutine variables
Posts: n/a
hi! everyone :

I want to use the wall subroutine for multiple rotation fram , but i can't find the means of the variables about 'TORHF' 'RESWT' 'RSTSC'.

I need to give the angular velocity (RPM) ,SO which varable i need to set.

Thank you for answer me !!

The meaning of the variables is explained in the file, which you will find in the ufile directory.

TORHF is Temperature OR Heat Flux. (depends on what you switched on in the boundary definition panel). RESWT is the value of the wall thermal resistance RSTSC is the value of the wall mass resistance (when scalars are defined)

If you have to impose a spin velocity at walls with a given RPM velocity, say given by OMEGA




PI = ACOS(-1.0)

INTFLG(1) = 1


U = 0

V = X * OMEGA * PI / 30.

W = 0

Please read the subroutine headings for more information. Keep in mind that the velocities are to be defined in the coordinate system set in the boudanry definition, here a cylindrical one HAS to be chosen).
