Advanced Numerical AnalysisEngineering and Innovation
Dr Andrew Mar is our head of discipline for Advanced Numerical Modelling and an internationally recognised expert in his field. Following a period modelling instability problems in the oil and gas industry, the last 20 years of his career have been dedicated to the numerical analysis of tunnels and underground space and he is currently writing the NAFEMS Guidance Book on Geotechnical Finite Element Modelling for Sprayed Concrete Tunnels.
Before embarking upon any analysis, we ensure that we carefully consider buildability and sequencing, and only then will we decide on our approach to the numerical analysis. In some cases, a simple 2D model may be perfectly adequate. However, where we have complex interaction between multiple tunnels, complex multi-stage 3D models using highly advanced constitutive models are essential.
