Error when setting solar-calculator

Andrew Berner

I'm currently working to develop the aerobody for our college's next solar car. The solar load model in Fluent has been very useful in helping assess how curvature changes will alter the power output from the solar array. I've been trying to create a journal that will use the solar calculator to determine the sun angle at a given location for half-hour intervals during the day. At each half hour, the sun vector is determined from the solar calculator and the illumination parameters are set using empirical data from the NOAA surfrad network. The mesh is initialized to perform the raytracing, and then a surface integral is taken over the array zone for the wall flux of reflected visible radiation. When using the TUI command to set the solar calculator in fluent 6.2.16 and 6.3.x, entering values for each prompt results in the error "Error: unbound variable" followed by "Error Object: %rp-var-value". This error halts journal execution, which is obviously problematic. Can anyone tell me what settings might influence this issue? Thanks.
