Emc2 develops specialty computational software often based on the finite element method for clients. This includes development of special purpose routines that interface with commercial codes to perform functions not capable within the code (USER Elements, USER Materials, etc.). In addition, Emc2 enhances open source software for specific purposes (e.g., WARP3D enhanced for weld modeling). Some examples of these developments, which are leased by many organizations, are listed below.
Virtual Fabrication Technology is a software calculating weld residual stress and distortion control. The VFT code helps control distortion, minimize residual stresses, and pre-determine welding parameters such as weld-sequencing, pre-bending, and thermal-tensioning, using material properties, consumable properties, etc. as inputs. By doing this, manufacturing companies avoid costly design changes after fabrication. Emc2 staff developed this software code over a number of years in close cooperation with Caterpillar Inc. (CAT) of Peoria, IL, who currently uses this code exclusively for all fabrication and product design and development activities worldwide. Emc2 has licensed VFT for a number of other applications including the nuclear industry (USNRC), national laboratories (KAPL), shipbuilding (USNAVY) and others
The Emc2PDFA (Pipe Ductile Fracture Analysis) program allows the user to predict unstable axial ductile fracture behavior in high energy pipelines. It calculates the ductile fracture arrest toughness values for high-energy natural gas pipelines for design purposes and predicts arrest or propagation behavior given a toughness value for assessing field failure data or full-scale burst test data.

PipeFractCAE is a special purpose FE mesh automated generator with GUI to calculate arbitrary-shaped stress-corrosion crack growth in pipes/plates/welds. Automatic update of FE mesh after each analysis run allows for much more rapid design optimization than traditional FEA optimization methods. It frequently conducts 200 to 400 FE analyses per case has the capability of 1000’s of FE optimization runs in same time that it takes to complete 2 or 3 runs with traditional methods.
ALT3D is a simpler method for determining crack driving force for arbitrary crack in any 3D geometry using only the initial un-cracked component stress analysis. It is currently licensed to several organizations.
