Z-set existing customer baseZ-set existing customer base
• Z-set products have been on the market for 10 years and has continuously grown in scope
• Almost exclusively “Enterprise” class CAE departments – mostly ABAQUS users
• Generally each client has 1-2 power users – many others in general application use
• Experience shows deployment to a wide scale is feasible for general CAE use
• In almost all cases Transvalor or NW Numerics provide a high level of customization
