Modes de ballotement

Hello everyone

I try to solve the sloshing modes in cylindrical tank. I create a cylinder in salome and make a hexahedron mesh. I then perform modal analysis on it. I refer to the exercise given in ADLV101 where shoshing modes are done on rectangular tank. I get good results when i perform on that geometry.But when i use the same command file with little changes for Cylindrical tank i encounter errors. I don't know why i get the error. Could anyone possibly tell me what is the probable mistake. I enclose my .comm .med and .mess files for your reference.

I tried to solve it but i get an error which i am not able to comprehend. Could any one suggest me as to why am i getting this error. I get the frequencies which are very vague and far away from theoritical result.

<EXCEPTION> <ALGELINE5_23> !

here are the .comm .mess and .resu files. I couldnt post the .med file because it exceeds the limit.
