Discontinuous results from imported 3D field data

fang yanwei

Hi,

When I import 3D field data in EDEM and query it via EDEM API, I get strange and discontinuous results (like picture below), which is far from the original field.

I tried to squeeze 3D field data into several 2D x-plane and the results truned reasonalbe. But I also loss plenty of field structure infomation by doing this.

Does anyone know how to solve this?

Thanks a lot!!!

Hi Fang,

How does the field data display in the EDEM analyst, could you show vector or contour plot of the data in the Analyst?

Hi Stephen,

Thank you for replying!

My original data has dense region and sparse region mixed, which I think is the most likely reason for the error. The plot of density in EDEM shows like the picture below. Only a part of the field is able to show.

Sliced data looks better, entrie field plot well.

Hi Fang, 

The field as shown in EDEM does look reasonable, when you query it with an API or with the in-build drag models EDEM takes the closes 8 points or vectors and then does inverse distance weighting function to get the point or vector to apply to the specified particle.

So I would expect some smoothing of the data, you can change the number of points to query or alternatively consider modifying the field so it is more uniform.
