Abaqus has a feature to record almost all of one’s operations in Abaqus CAE environment into script in format of Python language. This feature is called Macro Manager, detailed in Abaqus/CAE manual (Section 9.5, a html page).
Because of carelessness, I ran into a ‘problem during linking’ error in Abaqus. The mistake was misspelling a dimensional variable name. That caused the variable used had not been declared.
For a Traction Separation interface behaviour, there are three property values to be set: E/Knn, G1/Kss & G2/Ktt. I am looking for the method to determine/calculate the values.
My model with about 300,000 mesh elements run into an error after a little while of job starting, with the system error code 1073740940. It worked after I reduced the number of elements to about 150,000 with remesh. I am not sure whether this is a computer performance related problem. It’s worth a try when running into this type of error.
Abaqus 中提供了两种方式来模拟界面问题：1. cohesive element；2. surface-based cohesive behavior。其中后一种是在界面的两侧的两个表面之间定义一个相互作用（interaction）来模拟界面特性。
Abaqus error message “The interaction “Int-1″ references a contact property (IntProp-1) that contains the damage or cohesive behavior option. These options cannot be specified for this type of interaction.”
Typically, Abaqus has two methods for simulating the bonded interface behavior between two entities. One is Cohesive Elements, and another is Surface-based cohesive behavior. When thickness of the interface is negligible, surface-based cohesive method is recommended for its convenience and effectiveness.
When using Bottom-up Mesh in Abaqus, sometimes an error message of “boundary conditions reference regions which contains geometric entities that are not associated with a mesh” may pop up after submit the job. One of my colleague suggested following tip to solve it.
如何在 VUMAT 中确定处理的 Element 的序号？这是个有趣的问题。在 polymerfem.com 找到一个方法并附有解释。记录，暂无验证。
Abaqus 可能会提示有些 Elements 出现了过度变形，并提示可以通过 element set ErrElemExcessDistortion 查看。即使该模拟中途因错结束，也可以在输出中查看到这些单元。
