There are many possible causes. I suggest you post your model to the forum. Note: If necessary, you can reduce the size of your .mph file by selecting "study" from the top toolbar, then "clear all solutions" from the ribbon, then select "mesh" from the toolbar and then "clear all built meshes" from the ribbon. If you then save that file, it will almost certainly be less than 5 MB, so that you can post it to the forum.
