Hello,

I am trying to simulate a One-Cylinder ICE with Forte. My Problem is the following:

As you can see in the first Picture the Valves are closed, but there is a high velocity magnitude at my exhaust valves. The Temperature is more or less constant at the valve openings. 

I seated the Valves with the function `Seat the Valve` and i got to minimums from 8e4 mm  to 4e4  mm. Is that maybe too big and i have to change the geometry to make it fit better?

 Furthermore  the Simulation is really slow (2 hours for 1 CA). Is there maybe a connections between these problems? And is there a Solution for this ? For example an option to disable material transport through small gaps..

Thanks in Advance!

Hello, 

It would be difficult to diagnose this, but I am suspecting this to be a large mesh jump. To narrow down the cause of the issue, please make sure you have refined the mesh based on the best practices mentioned in the user guide: 2.3.2. Set Up Mesh Size and Mesh Refinement (ansys.com)
