Abstract
Purpose
This paper aims to provide a case study focused on the substitution through selective laser melting of a part typically fabricated by traditional manufacturing.
Design/methodology/approach
To exploit the additive manufacturing (AM) advantages, the retrieving of the reconfiguration part data was provided, the process strategies by means of the interchange file handling and pre and post-processing were investigated and a re-design of the part was developed. Finally, the fabricated part was tested and analyzed.
Findings
Results claimed that a reconfiguration of the manufacturing framework plays an important role at each step of the process otherwise many AM benefits can be lost. In the paper, a set of recommendations, suggestions and hints regarding the implementation of AM for part substitutions is provided.
Research limitations/implications
Many aspects of the AM adoption, such as the production cost, energy consumption, sustainability and production volume, depend upon the geometry, batch size and other impactful factors, and thus they need to be studied in a case-by-case manner.
Practical implications
The proposed approaches have the concrete aim to address industrial resources toward the maximization of AM benefits in part substituting.
Originality/value
In this paper, the substitution of a part is fully undertaken from the early data collection to the manufactured part testing providing integrated approaches for each process step.

Abstract
Purpose
To present a numerical method for the solution of the unsteady incompressible Navier‐Stokes equations in a generic setting.
Design/methodology/approach
The equations are discretized in space by the finite element method, and in time by a semi‐implicit finite difference scheme, using a fractional‐step method to enforce incompressibility.
Findings
The presented results demonstrate the satisfactory accuracy of the method in the simulation of vortical flows in laminar regime and the stability of the solution in presence of a strong boundary layer.
Originality/value
The successful integration of the CFD into the industrial design depends on its capability to produce accurate and reliable simulations of real life applications. These considerations drive the development of the proposed method: it can be used in conjunction with finite elements of any order of accuracy, providing accurate and numerically stable results for complex flows. Moreover, the computational requirements are low when compared with other similar strategies.

Abstract
Purpose
The main purpose of this study is to investigate perceptions about and contributing activities to business-to-business (B2B) brand value by corporate managers and local stakeholders in the context of emerging markets.
Design/methodology/approach
The case study examines brand strategies of a multinational company in the high-tech industry. By using NVIVO, this research analyses the brand narratives by corporate managers of Axis Communications in Sweden and local stakeholders in Russia, Brazil and India. The study evaluates perceptions about brand value and contributing activities emphasized by corporate managers, local managers, local partners and local end-customers.
Findings
The findings demonstrate that corporate managers underutilize contributing activities by local managers and other local stakeholders, despite these activities being central to enhancing brand value. This research provides insights into how corporate and local managers can develop successful brand strategies in emerging markets. Consequently, a general typology of contributing activities to B2B brand value by local stakeholders is proposed.
Originality/value
The company-centred approach to B2B branding stresses the importance of unique components of brand value and their consistent communication to multiple stakeholders. Prior studies provide limited evidence on how various stakeholders perceive brand value and enhance it through their contributing activities. Following the stakeholder-encompassing approach, this study advances branding research by examining perceptions about and contributing activities to B2B brand value by corporate managers and local stakeholders in a cross-cultural setting. Future studies are recommended to apply a stakeholder-encompassing approach in developed and transition economies and considering other relevant groups of stakeholders.
