Try calling fluent & evaluate their FiDAP and Fluent softwares... They are arguably the best in the business & have excellent technical support... I have used FiDAP for over 7 years for a wide range of problems in the semiconductor industry... FiDAP is accurate & reliable if you are willing to take the time to learn to use the software properly... They have recently added capabilities to address fluid-structure interaction problems also...
