<p><font size=2 face="sans-serif">Hey all,</font>
<p><font size=2 face="sans-serif">I'm experiencing issues with the calculator
filter. Basically I'm trying to create local_entropy_generation_rate=F(turbulent_viscosity
,space_derivatives_of_velocity_components) and I keep getting some kind
of error in vtkArrayCalculator.cxx, line 305, like "Invalid
array name: VectorGradient" or "Invalid array name: TurbVisc".</font>
<br>
<br><font size=2 face="sans-serif">I tried messing around with the cell-to-point
or point-to-cell data filters but it did not help. My initial input is
one single CFD dataset created by Code_Saturne. I can display the turbulent
viscosity and the derivatives of the velocity field as I wish, but I don't
manage to use the array data to create my entropy function...</font>
<br>
<br><font size=2 face="sans-serif">Any clue?</font>
<br>
<br><font size=2 face="sans-serif">Thanks!</font>
