<p>Back with another question!</p>
<p><br>
</p>
<p>I have a pipeline that has 1 input and 4 outputs. The simplest is a IntegrateVariables filter hooked up to the input. Another branch of the pipeline goes through several PythonCalculator filters and a CellDataToPointData filter and then arrives at the three
outputs:</p>
<p><br>
</p>
<p>1. The CD2PD filter is connected to a Contour filter with a single level, X. This is then connected to an IntegrateVariables filter (used to compute the area of the Contour) and a Writer.</p>
<p>2. The CD2PD filter is also connected to another Contour filter with a single level Y. This is connected to an IntegrateVariables and Writer just as in 1.
<br>
</p>
<p>3. The CD2PD filter is sliced two times with each slice in a different render view to save images.
<br>
</p>
<p><br>
</p>
<p>I have the coprocessor running every delta_t seconds. The initial IntegrateVariables filter is updated with UpdatePipeline and then the values are saved to disk. This works every step, no issues.
<br>
</p>
<p><br>
</p>
<p>I then call UpdatePipeline on both of the Contour and both of the IntegrateVariables filters in 1 and 2. I check if the 'Area' field in the IntegrateVariables exceeds a threshold, and if it does, I save the Contour's to disk as a VTK file. This is not working
correctly. <br>
</p>
<p><br>
</p>
<p>If I start the simulation from a point where the Contour's exist in the flow already, then everything works great and the Area field changes in time and it saves the Contour's.
<br>
</p>
<p><br>
</p>
<p>However, if the simulation starts without the Contours already in the flow, the Area fields stay zero forever. It's as if the pipeline isn't updating or something. I have attached the DoCoProcessing function used. I don't see anything immediately obvious
that would prevent it from updating or getting the correct values for the Area. <br>
</p>
<p><br>
</p>
<p>Am I missing something about how the pipeline or contour filters update?</p>
<p><br>
</p>
<p>Thanks,</p>
<p><br>
</p>
