What is VMAP?

VMAP represents the convergence of virtual prototyping and prototype testing. There are several parameters that cannot be modeled accurately in existing virtual prototyping tools and are dependent on experimental methods. VMAP bridges this gap between virtual prototyping and experimentation in product design cycle especially in the development of automotive, aerospace and energy systems. The system significantly improves productivity of product design teams by not only cutting costs and development time but also intangibles associated with inaccuracies in design.

VMAP is a versatile software platform powered by accurate and efficient algorithms, friendly user-interfaces, rich and fast graphics and supports industry-standard file formats.

VMAP is used in various design stages as a design, diagnosis and manufacturing quality assurance tool. As a platform, it powers applications in several industries. There are customized tools built on VMAP to meet the increasing demand for VMAP in different industries -automotive, aerospace, energy, civil engineering, marine, off-shore structures.
