Problem with motion

PrzemekN · February 19, 2018, 07:06

Hello,

I've got problem with a mesh motion. I'm trying to solve 3D mixing problem using AMI and I trying to use information from https://www.youtube.com/watch?v=rqrCqzuvxPY tutorial.

Could you help me? I can send my case on e-mail.

Hey Przemek,

I saw your post on the other thread and now I'm here. As I said I have no experience with cyclic boundaries and cases.
However I checked your logfile and saw the floating point exception. I currently have to deal with that too. Till now I was only able to find out that it has to do with the boundary conditions, especially with U, at least in my case it seems so.

I would suggest you to overlook your U file again. For example your inlet, is it supposed to be inletOutlet?
And maybe try running the case with U=0 to see if it is working or if you get another error.
That worked for me but I am still trying to find a way to make the case work for U>0.

Hi Eko,

thanks for your suggestions. I modified my case like in tutorial from Holzmann site. And now it works, but I'm still waiting for the result

Are you familiar with OpenFOAM?

Good to hear that it works. I am new to OpenFOAM as well, using it since december and never had to do with simulations before. So I am not really familiar with it since it has a very wide range.
Just know about the stuff that I need or the error messages I had to go through
