Re: Another approach to assembly solver (A2plus)

- Algorithm should start with searching parts directly related to fix parts. - So it finds in step 1 the part A5, C5, D7, been fixed to B6 - These are added to partial system 1 - It does not matter, that two branches are found (A5 is a separate branch), as Solver will not waste time if there is mor...

Re: Another approach to assembly solver (A2plus)

Hi at all, Find my proposal for partial systems of Manuel's crankshaft... .Crankshaft-partial-Systems.png . Edit1 Assume about 500 steps per partial system necessary to solve very exact. => 3000 steps about needed, fast and much more accurate as solving all together. It will be a little bit slower ...

Re: Another approach to assembly solver (A2plus)

Ok, I'm convinced that working with parental relationship makes sense than other linking methods. Meanwhile I have a code that traverses the connections and created father/children relationships between the rigids, including the distance from the fixed part. For example, this is the result for the 6...

Re: Another approach to assembly solver (A2plus)

I'm not good with math and din't really understood all the move and rotations code, so I would ask some questions to understand the solver concepts: What will be harder to solve: 1. An assembly with 100 parts all at once 2. Or solve parts 1+2, after that solve parts 1+2+3, after that 1+2+3+4 and so ...

Re: Another approach to assembly solver (A2plus)

assembly_6dof_analisys.PNG Thanks for the charts, it helps alot to see how it should work. Question to understand how do you think the 6dof should be computed since I don't have good results: If I don't follow the rule2, I will get all the parts added to the working list since all are interconnecte...

Re: Another approach to assembly solver (A2plus)

1) in an assembly at least one part must be marked as fixed 2) when creating a constraint always select as first the reference object and then the object that must be moved. 3) manually pay attention to recursive constraint creation There is a case where rule 2 can't be applied: Parts assembled as ...

Re: Another approach to assembly solver (A2plus)

All parts which are constrained directly to ANY fixpart (there could be more), I would place to the working queue (=partial system). I agree... Indeed. I do not agree. As part 6 is a child of part 2 and part 4, final placement of part 2 and part 4 is depending on relations to part 6 So part 6 has t...

Re: Another approach to assembly solver (A2plus)

Guys, a little brainstorming using Turro's chart: Cattura1.PNG Assuming the arrows are in both directions, since I don't want to follow the 2'nd rule of father->son relation, so lets say the algorithm don't know who is the father and who is the son... I start calculations from Part1 since it's fixed...
