Has anyone in the group used the sunspace option in eQUEST? I have tried it and it blew up in LOADS Following is the .inp description of the Sunspace:

Following is the error message

***ERROR***********************************************************************

In routine TEMDEV for ZONE EL1 North Perim Pl Zn (G.N6) on 2/10 hr 11 (InitialFlg = 0)

SUNSPACE INTERIOR-WALL calculations produced bad values:

CSSVEC (convection) = 0. CSSVEC (conduction) = 7294864.

This would cause a 262. degree ZONE temperature change. Values are being ignored.

Check wall definitions for errors and report this inp/lib/wth to DOE-2 support.

Any ideas as to where I went wrong?
