Assuming your scene scale isn't massive (units set to something very tiny)....I'm not sure why your sim would be less accurate at a couple meters away. Likely something else is going on. You can send the scene to support@tyflow.com if you want me to look at it.
Quickest fix would be to export the correct sim as a tyCache and then just move the tyCache object in space to the location you want it, so the sim itself will be the same and you just offset the cache. After exporting to tyCache make sure you set the tyCache object's coordinates to local so that it becomes moveable.
