#812: tensorspecial for ML_BSSN::phi is not set
 Reporter:  rhaas   |       Owner:     
     Type:  defect  |      Status:  new

 if I am not mistaken then the default parameters (conformalMethod == 0)
 make phi = ln(gamma)/12 a tensor density of type tensorspecial == "log"
 and weight 1/6. The weight is in the code, the special is missing. This of
 course breaks once one sets conformalMethod == 1 and actually re-
 interprets phi as W.

 Fix in the Mathematica script would seem to add
 SetTensorAttribute[phi, TensorSpecial, "log"];
 and to define a new grid function W with the proper type for the coformal
 case. Only should affect multipatch runs.
