Using the result of a simulation as a boundary condition for another one

[acarte_echever]

I want to know if the results of one simulation can be used as a boundary condition for another simulation.
In the attached image it is represented grafically. It is an aerodynamic simulation of trains, where the speed of the train is simulated by introducing air with velocity. In this case I want to simulate the case where one train travels one way and the other one the other way. I’ve try to introduce air both ways but te simulation doesn’t run, so I am trying to split the case in two simulations, first I have simulated one train and I want to introduced the results of the mid “wall” as boundary conditions for the second simulation. And my question is if thats possible.

Hi @acarte_echever, thanks for posting on the forum

Welcome to the SimScale Community

Unfortunately that’s not possible within our platform, however, I’ll ask my colleagues for input in case there is any possible workaround for you to achieve what you’re trying to.

Best,
Igor

Hi @acarte_echever,

I just wanted to reach out again for a quick follow-up on your situation: what you’re trying to do would be possible if you used a third party solution such as ParaView for analysis, retrieving the point data for that particular wall and inserting it as a table boundary condition (which should only work for velocity):

Does that help?

Best,
Igor

Ok, I’ll try.

Thanks for your help

Yes, you can use the velocity profile obtained from the first train simulation as boundary conditions for the second simulation with the other train traveling in the opposite direction. Ensure your simulation software supports this setup. Are you struggling to keep up with your assignments? I was too, until I found https://canadianwritings.com/. They offer high-quality writing services, and their papers are always well-researched and written. The customer service is great, and the prices are affordable. Highly recommend!

Thanks for the information, I appreciate you for taking the time to write it. You made my day
