I would like to find a FEA package suitable for analysing quasi-static and dynamic fluid-structural problems of liquid-filled silicone elastomer sacs. I understand that potentially suitable packages include ABAQUS, MARC and ANSYS. I also have a particular interest in fatigue and lifetime prediction analyses. In this area I have recently become aware of a specialised package (FLEXPAC)from MERL which is bundled with ANSYS pre- and post-processing software. I am very interested to know if any users have experience with this software. Any comments or general advice would be very much appreciated. Many thanks!!
