NastranFX

Nastran FX is an integrated finite element analysis program co-developed by NEi Software and MIDAS Information Technology, Co., Ltd. It is NEiNastran integrated with Midas FX+ modeler.

Hence, Nastran FX supports all basic and advanced analysis solutions like surface contact, nonlinear and optimization. Nastran FX provides more than 20 solutions for practical and efficient simulation with reliable results.

Seamlessly Integrated and Task-oriented Environment - Nastran FX provides complete FEA environment by seamlessly integrating pre/post-processor and solver. The environment is designed to completely support NEiNastran solver and hence is very task oriented.

Various CAD Interfaces and CAD Parameters Update

Nastran FX provides direct interface with various CAD programs. Nastran FX provides CAD parameters update using CAD API’s. CAD parameters update allows easy CAD model change and parametric studies to find the optimum design variables.

STEP, IGES, Parasolid
CATIAV5 (R7~R18), CATIAV4 (R15 ~ R24)
SolidWorks (2000 ~ 2007), UG (15 ~ NX5)

Practical Geometry Modeling and Clean-up

Nastran FX provides various geometry modeling functions for surfaces and solids along with practical geometry clean-up functions for CAD generated geometries.
• Auto-check and repair, NURBS simplification
• Merge or break faces and edges
• Search and remove sliver faces and short edges
• Search and remove pin holes in faces
• Check and remove duplicated faces and edges

High Quality Mesh Generation and Management

Nastran FX supports free and mapped meshing for surface and solids. Using various meshing algorithms, adaptive size control, element-based remeshing and manipulation functions, even novices can generate high quality mesh without hassle. Nastran FX provides various mesh grouping and management functions which can be controlled using Works Tree.

It’s possible to generate shell mesh using only quad, only tria or combines. Solid mesh can be done using hexa, penta & tetra elements or combinations.

Surface Contact Suited for Complex Assembly

Nastran FX provides auto contact pair search by solver, which makes contact analysis very easy for huge and complex assembly models. This function requires only checking option for applying contact condition for all solutions.

Surface to surface, surface to line contact

Contact definition – auto-search by solver, contact wizard, manual, etc.

Linear contact – weld (bonded), gap, static/modal

Nonlinear contact – material, geometric nonlinear
– weld (bonded), friction, sliding, rough, friction coefficient, stiffness, offset
