Finite Element Analysis FEA

---

With its wealth of physical models and efficient solution methods, Ansys FIDAP is the flow modeling tool of choice for applications such as polymer processing, thin film coating, biomedical, semiconductor crystal growth, metallurgy, and glass processing. Based on the finite element method, ANSYS FIDAP offers complete mesh flexibility and robust and efficient calculations. With its special, easy-to-edit scripting language, ANSYS FIDAP makes it easy to do repetitive parametric studies where automatic modification of material properties or operating conditions is required. ANSYS FIDAP is available for Unix/Linux and Windows workstations and is optimized for parallel processing.

CDH/AMLS is a revolutionary new software that dramatically reduces the cost of frequency response and eigenvalue analysis for large finite element models. In Automated MultiLevel Substructuring, a finite element model with millions of degrees of freedom is automatically divided into about 10,000 substructures arranged in a tree that has about 20 levels. The model is transformed to a very efficient and accurate representation in termCDs of substructure eigenvectors. This method reduces the analysis burden greatly by reducing the computation required thus enabling workstations and multiprocessor computing platforms to be used and reducing disk space requirements and job turnaround time.

 

CDH/AMLS has been implemented with an interface to MSC Nastran, MD NASTRAN, NX-NASTRAN and OPTISTRUCT software so that it can be used in industrial vibration analysis. CDH/AMLS can be used in normal modes (NASTRAN SOL 103), modal frequency response (NASTRAN SOL 111), modal transient response (NASTRAN SOL 112), and structural optimization (NASTRAN SOL 200) solution sequences. Either use requires a minimum of effort on the part of the user; the user must add only two lines to an input data file to convert a standard Nastran job into one that uses CDH/AMLS. Once the system matrices have been assembled by Nastran, the Nastran job calls CDH/AMLS software for the compute-intensive portions of the analysis, and results are returned to Nastran for postprocessing if necessary. Alternatively, the analysis may be continued in CDH/VAO, a state-of-the-art interactive dynamics analysis program.

 

• Comfortable and easy usage
• Compatible to NASTRAN and other solvers
• High Accuracy
• Drastic Reduction in computer and hardware cost
• Impressive Performance leads to shorter elapsed time and higher productivity
• Reduction of FE-modeling cost by using one master model for multiple analysis disciplines, e.g. Crash-, Static- and NVH-Analysis.
• Make higher frequency range analysis feasible

Finite element analysis (FEA) is a critical part of the virtual design process. But because most FEA programs are linear, they can only study parts that deform a small amount, certainly not enough to deformation to exceed the linear elastic range of the materials.

But MSC Marc has no such limitations. A nonlinear FEA program, Marc enables you to assess the structural integrity and performance of parts undergoing large permanent deformations as a result of thermal or structural load. The types of deformations the program can study include geometric nonlinearities (metals bending) and material nonlinearities (elastomers and metals that yield under structural or thermal loading). You can also use Marc to simulate deformable, part-to-part or part-to-self contact under varying conditions that include the effects of friction—critical for analyzing nonlinear behavior in tool-and-die set-up, spring coil clash, or a windshield wiper system.

And 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 175 elements for structural, thermal, and fluid analysis.
