Overview

Marc is a powerful, general-purpose, nonlinear finite element analysis solution to accurately simulate the response of your products under static, dynamic and multi-physics loading scenarios. Marc's versatility in modelling nonlinear material behaviors and transient environmental conditions makes it ideal to solve your complex design problems. With its innovative technologies and modelling methodologies, Marc enables you to simulate complex real world behavior of mechanical systems making it best suited to address your manufacturing and design problems in a single environment.

With the solution schemes that are smarter and designed to provide the performance that you need by taking full advantage of your hardware combined with an easy to use modelling solution, you can truly discover and explore nature's inherent nonlinearities. Whether your problems involve large deformation and strains, nonlinear materials, complex contact or interaction between multiple physics, you have reached the end of your search and with Marc, you can now focus on your improving your designs.

Key Features

Easy to Use, Integrated User Interface

Marc's integrated user interface is designed to enable even the novice users to set up and solve complex nonlinear problems in a short time. Users can go from a CAD file to a complete FEA model and post- processing of results in a single integrated environment.

Contact Analysis for Realistic Assembly Analysis

Smart contact algorithms and modelling procedures implemented in Marc provide you with the accuracy you need while saving you the hassles of model setup that are generally associated with contact analyses. The segment-to-segment approach provides you with an even better way of contact modelling by overcoming traditional limitations of master segment-slave node approach. Taking friction and friction generated heating is also quite easy with Marc, enabling you to focus on capturing accurate physics.

Nonlinear Material Models for Accurate Results

Whether you are designing with glass, rubber, steel, or concrete, Marc offers an extensive library of metallic and non-metallic material models, along with a library of nearly 200 elements for structural, thermal, multiphysics and fluid analysis. Elastomeric materials can be represented with popular material laws including Generalised Mooney-Rivlin, Boyce-Arruda, and Ogden using built-in curve fitting capability that computes coefficients from stress/strain data. Multiple models are also provided for plastic behavior, and specialized element types automatically address numerical issues like hour-glassing to get converged, accurate solutions to large strain problems. Customisable engineering materials like composites, powder materials and shape memory alloys can also be modeled and analysed using Marc enabling you test your new materials prior to their implementation in new designs.

Adaptive Meshing for Improved Convergence

When large strain distorts elements, or changing contact conditions make a finite element mesh inappropriate to capture true contact with other components or bodies, Marc automatically remeshes within time steps of the solution to ensure that the solution converges on an accurate solution. Some of the most difficult nonlinear problems have been successfully solved with Marc and adaptive meshing, including oil packer seals, wire crimping, and elastomeric seals. This automatic approach saves considerable time spent on mesh manipulations to achieve a solution.

Multiphysics for More Reality, Less Approximation

Increased reliance on simulation in design and development necessitates consideration of all the applicable physics to ensure accuracy of the model. While single physics models have long been used to tackle these problems, the disconnected manner the various physics are handled could lead to errors in response prediction and thus lead to inefficient designs. Often, influence of non-structural physics phenomena on structural behavior is required. Heating of an electric wire and its influence on adjacent structure's deformation, microelectronic mechanical systems (MEMS) are just a few examples where the coupling comes into play.

The multiphysics capabilities of Marc, when used with its superior nonlinear structural analysis capabilities, provide more accurate results leading to better and improved designs of your structural systems. Marc can be used to couple structures, thermal, fluid (laminar, small deformation), magnetostatics, electrostatics, and electromagnetics. The coupling capabilities are also highly useful in accuracy of manufacturing simulations like welding, curing, and forming.

Parallel Processing for Accelerated Product Design

Parallel systems and multi-core systems are quite common these days. Long before they have become common-place, Marc's researchers invested time and resources in parallelising Marc. Marc's parallel analysis capabilities have been available for nearly 15 years and are field tested quite extensively. While most solvers focus on parallelising only one aspect of solution (namely, matrix solution), Marc parallelizes all the steps of analysis (assembly, matrix solution and stress recovery). This enables you to get more out of your hardware.

Failure Analysis for Reduced Warranty Costs

One of the most challenging tasks of design and development process is prediction of failure. Without knowledge of how a structure might fail, it is harder to improve its safety performance. Physical testing for all possible failure scenarios can be cost prohibitive. Marc provides a comprehensive list of failure models suited for several material classes, including ductile, brittle, composites, elastomers, and concrete. Crack propagation capability enables engineers to better grasp the failure mechanisms and device appropriate methods to avoid catastrophic failures.

Manufacturing Analysis for Material Savings

Success in simulation of a manufacturing process is governed by a product's strength in nonlinear analysis capabilities and multiphysics, especially thermal-structural coupling. Marc's superior nonlinear solution aided by its ease and robustness of contact and automatic remeshing make it an ideal solution for simulating manufacturing processes like various forming operations, forging, welding, quenching and curing.

Integrated pre/post-Processing for Ease of Use

The integrated user interface of Marc is designed for nonlinear analysis, and hence provides the tools and utilities that enhance user experience. From CAD import to post-processing, menus and forms are created to provide ease of use to the users. Special tools for meshing, result mapping, and result extraction and interpolation also help improve user productivity.
