<div dir="ltr"><div><div><div>Hi,<br><br></div>The mask points filter gets rid of all of the cells so there is no way for the stream tracer filter to find velocity values at arbitrary points in the domain. The best way is to find a machine with more memory to run on. Barring this, you'll have to reduce the size of your data set in some way that keeps some type of cells. The best way I can think of is to use the clip filter, then cell data to point data and then finally the stream tracer filter.<br>

<br></div>I am trying to use the StreamTracer with custom source on my dataset, but my Dataset has 100,000,000 cells.<br>
<br></div>First StreamTracer with custom source is not active on cell data so I had to convert using "Cell Data to Point Data" filter.<br>
<br></div>Then, as my dataset is so big, I can not apply the "StreamTracer with custom source " directly on top of "CellDataToPointData" filter, so I tried to use "MaskPoints" to reduce the number of points to 5000 and then apply the filter.<br>
<br></div>I am trying to draw the velocity field in a cube. The velocity vector array seems to have passed to the Mask Point as I check in the Information tab of the Mask Point filter, but then I donīt see any thing. I have also checked the following in the Mask Point filter:<br>
<br></div>1. Proportionally Distribute maximum number of Points<br></div>2.Random Sampling<br></div>3. Generate Vertices<br></div>4. Single Vertex per Cell<br><br></div><div>In the MaskPoints I can see the 5000 Points created if I switch to the Point View.<br>
</div><div><br></div>Also in the StreamTracer I am using all the defaults. I tried changing the Maximum Steps, but it didnīt have any effect.<br><br></div><div>Could anybody please tell me what is my error in this procedure?<br>
<br></div><div>Thanks a lot<br><br></div><div><br><br><br></div><div><div><br><br></div></div></div>
