Engine running with A2Plus

Postby dcapeletti » Wed Apr 10, 2019 7:56 am

Hello,
I just saw this example using Assembly 4. It's an engine assembled and running.

https://forum.freecadweb.org/viewtopic. ... 06#p293179

Since the design files are available in the ASM 4 repository, it wouldn't take too long to do the assembly. You only need to design the crankshaft, make an assembly and make a script to move the crankshaft which moves the whole assembly.

Is anyone encouraged to do so?
I'll try it in my free time. I listen to suggestions or recommendations.

Thanks

I made the engine and the assembly with A2Plus. The camshaft is still to be finished. You can see the GIF to see the animation in operation.

Thank you very much.

What I'm trying to do is make the animation run a little faster. In a thread I was recommended to deactivate the following lines https://forum.freecadweb.org/viewtopic. ... on#p264362 and it has worked, but it is still a bit slow.

My animation code is as follows https://gitlab.com/dcapeletti/ejercicio ... /README.md

Hi Diego,
good work ! :D

A2plus is not really a simulation WB, as it's solver is python based ATM. Therefore it can not compare with solvers written in C.
Perhaps this will come in future.
