It seems that you're using wrong names.<br><br>The name of the only data that you can use in the formulas are available under the buttons "scalars" and "vectors" in the calculator filter. <br>If you don't see anything, no variables is stored at the points of your dataset. <br>
<br>You can see the data stored at the center of cells by into the information tab.<br><br><div class="gmail_quote">2010/10/26 Jean-Baptiste Leydet <span dir="ltr"><<a href="mailto:Jean-Baptiste_Leydet@whirlpool.com">Jean-Baptiste_Leydet@whirlpool.com</a>></span><br>

<p><font face="sans-serif" size="2">Hey all,</font>
</p><p><font face="sans-serif" size="2">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 face="sans-serif" size="2">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 face="sans-serif" size="2">Any clue?</font>
<br>
<br><font face="sans-serif" size="2">Thanks!</font>
