Recently, I often do some cold plate structural analysis, involving thin plate modeling. Although I have tried to use Shell units for analysis, the stress and displacement results of Shell units are larger than those of Solid units, and it is more likely that the calculation will not converge when it comes to contact problems. Fortunately, Ansa provides a way to generate a body mesh by stretching Shell units, which can quickly generate a Solid mesh through Shell units, greatly saving modeling time.

1. Related commands

In Ansa, the following commands are commonly used to set contact for Abaqus:

2. Contact pair

The most commonly used contact pairs are generally created by calling up the creation dialog box through AUXILIARIES → CONTACT → CONTACT .

Common settings are generally as follows:

After using Ansa to output the inp file, you can submit the inp file for calculation through the Abaqus CAE window interface, or you can submit the calculation through the command line. You need to add the Path when submitting using the command line. In Windows, it is usually the path [Abaqus installation directory]\Commands.

In fact, after installing Abaqus in Windows, the Abaqus Command shortcut will appear in the start menu. Clicking this shortcut can submit the abaqus calculation file through the command line without adding the Path.
