Dear Developers,

i am using 6.5.171 version of dream3d. My goal is to study the influence of shape of precipitates, hence i would like to keep grain structure unchanged for test on different shapes. 

I have tried read grain structure dream3d file, then use StatsGen (and other filters) to insert precipitate. However it cannot be done. Is this kind or pipeline possible? My pipeline is attached for reference.

Thanks!

Best regard,
Yi

Dear Developers,

I think i solved the problem by just giving a dummy matrix and then insert the precipitate as normal. It looks like doing the desired thing. My pipeline is attached for reference in case anyone has the same problem as I. Any comments from the experts are also appreciated. Thanks!

Best,
Yi

I think what you could possibly do is to run the pipeline through “Pack Primary Phases” then save the .dream3d file.


Then start another pipeline. Use a “Read DREAM3D File” filter to load up that first file, then continue the pipeline with everything after pack primary phases. This will keep the grain structure constant but rebuild the precipitates. When you read in the .dream3d file do NOT read in the StatsDataContainer, but instead copy the StatsGenerator filter from the previous pipeline into this second pipeline as the second filter. Now add the other filters for “Insert Precipitates” and those that would normally follow that filter. This should allow you to adjust the values in StatsGenerator to influence the precipitate shapes for each run of the pipeline.
