viennats / viennats-dev Goto Github PK

Which version of VTK does Viennats-dev require?
During the installation process when I go to the "make" step ,why is it displayed "Vtkobject.h: 56:44 error: extra '; ' and vtkAlogorithm.h;57;39;error: extra ';'"?

I want to perform etching with SF6_O2 plasma with SiO2 set as mask. So I am trying to set up the SiO2 mask shape and the Si hole shape, but I am struggling because I don't know how to use dx and vtk files. How can I set up the initial shape of the mask?

I have tried to build this repo under ubuntu, and succeeded.
I need to build it under windows but failed.

When I used cmake to build this repo, I got such problems.

Could you give me some instructions to fix this? Thank you very much.

If all active points in a levelset are removed, even if other active levelsets are still present, and a volume is exported, the volume output throws a size error.

Hello everyone.
Could you please provide a focused ion beam example ? It's hard to figure out using just a user guide.

I use ViennaTS instead of ViennaPS because the code is easier to understand. However, I am having trouble finding any manuals or other information on etching with SF6_O2 plasma in the Examples. Please let me know how it is possible.

The function thin_out() first distributes the number of defined points across cores and then deletes those points that have LS values higher than 0.5. This results in the last core getting a very small number of points. Calling the function twice in a road results in good load balancing as no points are removed after setting the segmentation.

Example:
thin_out_example.zip

Number of points per thread, for 4 threads:
-->After first call: 41, 41, 38, 2
-->After second call: 31, 31, 30, 30

When outputting a geometry with "output_volume", some edges have holes along them. This row of triangles seems not to have been outputted.
=> there are surface elements but only very small ones not closing the surface:
seems to be a problem with the levelset values at the edges of geometries leading to triangles too small to close the boundary; missing triangles lie outside the boundary and cannot be outputted.
