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.”
Surface-based cohesive behavior 用于模拟 bonded interface。 但是它不用用于 Surface to Surface Interaction. 否则会遇到错误提示，”Surface based COHESIVE BEHAVIOR cannot be used for contact pair interactions. See the surface iteraction named INTPROP-1.”
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.
VUMAT can be implemented to a model which has more than one user custom materials, using cmname variable to identify the materials.
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.
To obtain more insight into the stresses and strains of a loaded structure we may want to view results along a line rather than a point. This can be achieved by defining a path and then plot throught the path.
Abaqus 早期好像是只有通过命令行提交任务的。即使到了现在，很多人还是喜欢直接通过命令行操作。而且有时候需要用命令行提交 inp 文件进行计算还可能是因为少数 keywords 不为 Abaqus/CAE 识别。
