first Internal Engine simulation with STAR-CCM+

Weisser

Hi

I made a ICE engine simulation with STAR-CCM+.

I prepare different meshes (volume representations) at different positions and cranck angles. Then I compute on one postion for few timesteps , mesh replace the next one. STAR-CCM+ maps the solutions.

I added relevant compressibility terms and momentum sources using field functions and java macros.

It is really easy to set up but it is a bit expensive on the disk because there are a lot of meshes to prepare in advance. So I only did this 2D. I see well the Otto cycle at the end:

The full technology is nearly there. What is missing to the code is the spray injection and moving the vertices between position. It also work with LES.

Has anyone tried moving meshes or engine simulation with STAR-CCM+?

Thanks,
