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 modeling nonlinear material behaviors and transient environmental conditions makes
it ideal to solve your complex design problems. With its innovative technologies and modeling
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 modeling 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.
 New User Interface |
|
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. |
 Segment to Segment Contact Analysis |
|
Contact Analysis for Realistic Assembly Analysis
Smart contact algorithms and modeling 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 modeling 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. |
 Extensive Library of
Metallic and Non-metallic Material Models |
|
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 Generalized 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. Customizable engineering materials like
composites, powder materials and shape memory alloys can also be modeled and analyzed using Marc
enabling you test your new materials prior to their implementation in new designs. |
 Marc Automatically Remeshes
to Ensure an Accurate Solution. |
|
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. |
 Marc can be used to Couple Structures, Thermal, Fluid,
Magnetostatics, Electrostatics and Electromagnetics. |

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 parallelizing Marc. Marc's parallel
analysis capabilities have been available for nearly 15 years and are field tested quite extensively.
While most solvers focus on parallelizing 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.
