Hi fellow foamers,
Problem description: I'm trying to represent the non-dimensional temperature , throughout a 2D channel in Paraview, in which is the bulk temperature for the transverse surface positioned in the longitudinal coordinate. in the present case is constant. The bulk temperature for a section, , in a given longitudinal coordinate is given by , where is the fluid density and the velocity component normal to section . Achievements so far: So far I've been using swak4foam's funkyDoCalc coupled with a bash script to cycle through the longitudinal coordinate in order to create an array of the bulk temperature along the channel. The swak4foam script: Code:
s1 { type swakExpression; valueType surface; verbose true; expression "sum(T*rho*Sf()&U)/sum(rho*Sf()&U)"; accumulations ( average ); surfaceName x1; surface { type plane; source cells; surfaceTupe searchablePlate; planeType pointAndNormal; pointAndNormalDict { basePoint (0 1e-6 1e-6);//the bash script uses sed to change the x coordinate of the basepoint normalVector (1 0 0); interpolate true; } } } Up to this point I have an array of the bulk temperature throughout the longitudinal coordinate. Current obstacle/issue: I want to map this bulk temperature array to a scalar field, in which , i.e., for a given longitudinal position, , the transverse temperature is set to the correspondent bulk temperature for any transverse position. After obtaining this bulk temperature field I could then use the Calculator function in Paraview to determine the non-dimensional temperature field . All help is welcomed. Thank you. |
