A third example will be on the assessment of retrofit options, for a welded structure containing cracks that developed after initial welding. Abaqus Unified FEA is the leading finite element. Diagnose, and visualize advanced Abaqus analyses. The intuitive interface. Or crack propagation in.

ABAQUS Welding Interface - Minimum Temperature less than Predefined Field
All predefined fields are set to 21.1 degC including initial base temperature. Temperature dependent properties, constants, etc are all dimensionally consistent.
Could it be the mesh is not fine enough? See attached.
Thanks!
UPDATE: I removed all temp dependent properties as a test and still has a similar result with elements dropping below the pre-defined field.
UPDATE 2: I noticed my temp dependent properties went up to 1400 degC but temp application of 1500 degC. I applied temp of 1400deg C but still same results with elements dropping below pre-defined temperature field.
Abaqus has always been a software of choice for modeling welding in various industries. This eSeminar will highlight the capabilities of the Abaqus Welding Interface (AWI), including some recent enhancements that make realistic simulation of the welding process possible in Abaqus.
The Abaqus Welding Interface (AWI) places an emphasis on the ease of weld model preparation and setup while supporting options and features that allow realistic predictions of quantities of interest such as distortion and residual stresses. A flux-based energy input option using the Goldak double ellipsoid model is now available for use with the AWI.
Another significant enhancement takes advantage of the new, strain-free element activation technique developed by SIMULIA R&D that has applicability in many important areas, including welding. This new technique improves pre-processing and analysis performance significantly for models of processes involving material deposition such as welding and additive manufacturing. As a result, strain-free element activation is no longer a step-dependent feature.

- Abaqus Welding Interface. I want to simulate a 3D welding in Abaqus 6.14.1 and I'm not good enough in coding to work with Subroutines. I need a new version of this Plug in. For more information.
- Abaqus Welding Interface Crack This example examines the inertia friction welding process of the pipes shown in. The specific arrangement considered is the resulting as-welded configuration shown in.
- The ductile fracture model of interface crack in dissimilar weld joints was built by adopting extended finite element method; the propagation characteristic of interface crack was summarized. The results indicate that the strength mismatch of materials at sides of interface will increase trend of crack advancing into the relative soft material.
