Re: Using Gmsh as triangulator for CAM

Does anyone have much experience with using Gmsh? Could it be run against OCC bodies easily to generate the triangulations? GMSH is one of the two meshers used in FEM workbench, there you can easily access and use it (also for 2d triangulation). Have a look at FEM_MeshGmshFromShape . If you want to...

Re: FreeCad 0.19 inhibits desktop during STEP (.stp) file load.

Ah, I understood the post differently, thougth it's about using 100%CPU and with that locking up the other UIs. If its grapping some systmem inputs you are rigth, that would be a bug.

Re: FreeCad 0.19 inhibits desktop during STEP (.stp) file load.

This should, in my view, never be so. The slowest things are us, and our mouse, and our typing. The highest priority should be given to the slowest stuff at an acceptable sample frequency. The interrupt is tiny, from when it can return to the really big task. We should never feel out of control, lo...

Re: [BUG] Line.intersect / intersectCC between colinear line -> Segmentation fault

As it is a regression one could also report it on the occ bug tracker, usually those regressions are fixed by them.

Re: Question about beam calculation with calculix

I intuitively assumed the beam is calculated with the profile I specify, and the 3d option is only for visualization purposes. So like a normal hand calculation calculix calculates bending moments etc. from the beam, and deflections and stresses than from those moments and the profile. If this optio...

Question about beam calculation with calculix

Hello, I'm calculating simple beam structures to analyse deformation and stress in profiles. The calculix solver has the option to choose 3d for output which allows for stress visualisation, compared to the 2d output. However, I also noticed different results dependent on that setting. For a very si...

Re: How to reference objects ? PropertyLink and DAG constraints

The bidirectional graph is implemented, however, it is only useful to calculate inlist and outlier faster. There is still the restriction of non cyclic graphs, and this will lead stay: if there is a cycle in the graph as in your example it is unclear how the execution order of the document should be...
