Geometry conversion from Solid Works to Binary/ASCII STL

Submitted by Mreza on Mon, 06/20/2016 - 20:06

Hello, I’m trying to incorporate LIGGGHTS for simulating a specific type of powder mixer. I’m using SolidWorks 2016 for creating the 3D geometries involved. In addition, I’m utilizing Paraview for post-processing purposes. Having read the user manual for LIGGGHTS, from what I understood the geometry files used in the execution script must be saved as ASCII STL format and that LIGGGHTS does not support Binary STL formats. When I attempted to open the ASCII files in Paraview the software stopped responding. Therefore, I can only view Binary files in Paraview. As a result, Every time I create a 3D geometry in SolidWorks I save my parts in both the Binary and ASCII STL formats. The main issue that I’m having is that whenever, I open my 3D geometries in Paraview the origin of the 3D models have been altered and therefore the geometries are not aligned properly. I was wondering if this issue is due to the conversion process from SolidWorks parts to Binary/ASCII STL formats.

Hi Mreza,

I think the issue with Paraview opening STL can be solved. Google for "paraview export LC_ALL=C"
