Sir, Thankyou for helping me. My mesh is completely loaded in the fluent. There is no problem in my mesh. When i try to run the calulation the fluent window will shut down automatically and the workbecnch shows the error which i mentioned above. As you suggested i try to do some other simulation( nucleate boiling) and and it calculate completely and shows the result.
I put some pictures of film boiling which shows the problem..png)
