OpenModelica VS OpenFOAM

I have used https://openmodelica.org/. It's another one of those "invest substantial time understanding what they are doing, and you will likely be rewarded." Simple things are simple, but I found it took longer than I would have like to bang out e.g. a PID algo with a particular motor and load. If you want to try this, buy the book, and follow it to the end. Then keep learning, as you build more and more... - Source: Hacker News / 11 months ago

If the robot simulation doesn't need to pick up stuff or take into account changing contacts with other objects you can use Modelica's Multibody library which you can run for free with OpenModelica. This will be more accurate than other simulators because modelica can analytically solve the dynamics equations. You don't need to write them either just to connect blocks for various components.

OpenModelica consists of a combination of graphical and written components to simulate dynamic systems. I don’t know what control system feature set might be available. AMESIM is a more extensive paid tool that operates on the same Modelica modeling language. IIRC, at least Simuscape operates on Modelica under the hood. Source: about 1 year ago

It shouldn't be too difficult to model in Modelica. You could approximate the pendula in 1D with masses on springs or just use Modelica's multibody library. Source: about 1 year ago

Modelica is a good start, at the very least in showing how to break a complex machine with many physical phenomena into components. Modeling accuracy and ease are generally opposed. Https://openmodelica.org/. Source: almost 2 years ago

In openfoam.org, there is not compiled binaries for Debian (any version). So one should install it using docker (I prefer to do not use it) or by compiling the code from the source. I consider compiling from source, but I do prefer binaries. Source: 10 months ago

Hello I am a mechanical engineering student in my last year. So I made the wisest decision to learn OpenFOAM. But there is the catch. I have no idea how to use Linux or how to emulate Linux on Windows 10. I found a lot of videos on Youtube how to download an start OpenFOAM but every one of them was using different methods each time so I got confused. Can anyone please help or direct me? Thank you for your answers... Source: about 1 year ago

As far as air flow simulation, I got slightly farther with Open Foam than I did in FreeCAD directly. Still, I got in way over my skill level and stopped before getting anything useful. Source: about 1 year ago

There are two versions of openfoam, one closed source (which is the one I linked to in my original comment, my apologies about that) and the open source version. But what you're describing makes it sound like fenics might be your best option. Source: over 1 year ago

I suggest you install per the instructions at openfoam.com or openfoam.org instead of using apt. Source: over 1 year ago
