Region used for material orientation assignment can also be used in meshing a part. Here is an example of messing a part using C3D8R element.
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.
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.
