Purpose: Purpose of this paper: Actually, in automotive industries one of the most important activities in product design is the evaluation of various events (i.e. crash events) using FEM simulation; in this context, software independence, that means to obtain the same simulation results on the same car-model using different FEM solvers, will be useful for reducing virtual prototyping time and consequently Time To Market. Design/methodology/approach: Development of a software-indipendence translation method is the aim of this work, which is an input data translation by a methodology independent of the FE calculation environment and allows reducing drastically the product development time. This methodology will be developed writing ad hoc a routine in Matlab language, that carries back in LS-DYNA environment the cards written in RADIOSS environment, helped by TextPad editor and completed by pre-processor Hypermesh.

Practical implications: Most of crash simulation models are developed in RADIOSS environment, but the LSDYNA environment potentialities exploration has increased the simulations demand using LS-DYNA software; therefore the development of a translation method like that meets this requirement. Originality/value: For product designers, the development of a translation methodology, that allows to carry back in a software environment the Know How developed for another software environment, will be very useful (We’ve to remind that often many design tasks of a project are made in outsourcing way).

Abstract

Purpose: Purpose of this paper: Actually, in automotive industries one of the most important activities in product design is the evaluation of various events (i.e. crash events) using FEM simulation; in this context, software independence, that means to obtain the same simulation results on the same car-model using different FEM solvers, will be useful for reducing virtual prototyping time and consequently Time To Market. Design/methodology/approach: Development of a software-indipendence translation method is the aim of this work, which is an input data translation by a methodology independent of the FE calculation environment and allows reducing drastically the product development time. This methodology will be developed writing ad hoc a routine in Matlab language, that carries back in LS-DYNA environment the cards written in RADIOSS environment, helped by TextPad editor and completed by pre-processor Hypermesh. Findings: The translation could be executed using the pre and post-processor Hypermesh and the RADIOSS model card manual correction, but this way to operate increases greatly the Time To Market, although today is the only method used in the most important Italian automotive industry. Research limitations/implications: A Software independence in Virtual Prototyping could help to accelerate several processes. The need to reduce costs and to increase quality is nearly obvious. Practical implications: Most of crash simulation models are developed in RADIOSS environment, but the LSDYNA environment potentialities exploration has increased the simulations demand using LS-DYNA software; therefore the development of a translation method like that meets this requirement. Originality/value: For product designers, the development of a translation methodology, that allows to carry back in a software environment the Know How developed for another software environment, will be very useful (We’ve to remind that often many design tasks of a project are made in outsourcing way).
