First step - tutorial 11 in STAR-CD. The other cases can help you with some ideas how to set the model, even they are performed using other codes. In this case you will need to make 3D model, because you will have effects on all sides of the train. The final model should be 3D train entering tunel, transient case. Good luck!

Thanks for all your help and suggestions! I will post more questions if I have, thanks again! Regards Christos

Taking the example of tutorial 11, if you can have very fine mesh at the rear side of train and relative coarse mesh at the front side of train, then when the train moves, you just adjust the mesh by mesh movement.
